Installing or Removing Eye On Sunrise

Installation

Removing Eye On Sunrise


Installation

Eye On Sunrise includes a setup routine that must be used to assure proper program operation. The setup routine follows all standards and conventions for proper file location and version checking.

You will need a copy of the file VBRUN300.DLL to complete the installation and to run the program. This file is usually not included with shareware programs on bulletin boards as it saves you a considerable amount of time and expense in download time if you already have it. You only need the one copy for any programs that require it. If you do not already have it on your computer, you will need to download it from a bulletin board or obtain it from your shareware vendor. Once you have obtained it, copy it to your \Windows\System directory before proceeding with the installation. Otherwise, the installation will not be successful.

To install Eye On Sunrise, place a blank formatted high density floppy disk in drive A: or B: and extract the files from the archive file to the floppy disk (the archive file is usually named EOSUN.ZIP -- the single file you downloaded or received from a vendor). Once all the installation files are located on the floppy disk, run Windows and from the Program Manager, select FILE-RUN and for command, type

A:SETUP                 or

B:SETUP

and press <ENTER>.

You may also extract the archived files to a scratch or temporary directory on your hard drive and run the setup routine from that directory.

DO NOT EXTRACT THE FILES TO YOUR \WINDOWS DIRECTORY!

After the setup program initializes, you will be presented with a suggested drive and directory for the permanent program location. You may accept the default, or enter a drive and directory of your choice. If you do not accept the default, you should enter the name of a new directory. If you install the program to an existing directory that contains other files, it will be more difficult to delete Eye On Sunrise if you decide you do not want to keep it. After that, installation will be automatic and upon completion, a new program group and programs item will be created for you. If you wish, you may then drag the program items to an existing group or your startup group and delete the new group that has been created (consult your Windows manual for details).

The setup program will copy the majority of files to the directory you have created through the installation program. Additionally, some files will be copied to your Windows and Windows System Directory. A list of these files may be found in the next section, Removing Eye On Sunrise, should you care to delete the program. Eye on Sunrise does not modify your AUTOEXEC.BAT, CONFIG.SYS, WIN.INI OR SYSTEM.INI files. The installation uses version checking and will not overwrite newer versions of some files if the version on the setup disk is an older version. We strongly recommend you follow accepted Windows practices in the location of the various files. If common files (e.g. link libraries like DLLs and VBXs) exist in multiple locations rather than in a common location (usually the directory \WINDOWS\SYSTEM), you can have problems and strange errors including GPFs if an older copy happens to be loaded in memory when you run a program that requires a later version. These kinds of problems can be very difficult to track down. Use of a setup program that uses proper versioning techniques is the best way to assure trouble free Windows operation.

NOTE: If you are running a substitute shell in place of the Windows Program Manager, you may receive a DDE time-out message upon completion of installation. Simply choose CLOSE at this dialog and the installation should still be successful. If you have other difficulties, try the installation with the Windows Program Manager running before calling for technical support.


Removing Eye On Sunrise

To remove Eye On Sunrise if you no longer want it on your computer, first erase any files in the Eye On Sunrise directory and then remove the directory using the Windows File Manager or with DOS commands.

Use the Windows Program Manager to delete the program icons and the program group if applicable.

Eye On Sunrise creates a file in your Windows directory called EOSUNRIS.INI. Delete this file using program manager.

The following files may have been installed to your Windows/System directory. Please note that these files may also be used by other programs. You should delete them only if you are sure no other program on your system uses these files. If you are unsure, copy them to a "scratch" directory or to a floppy disk before deleting them. That way, if it turns out another program uses them, you can get them back.

VBRUN300.DLL (this file is required for all programs written in Visual Basic version 3.0. It is recommended you do not remove this file as many other program you have or may get down the road will need it).

Multi-user Access

Multi-user network access or multiple instance access (running more than one copy of the program on the same machine) is part of the design specification of the database as long as the network is DOS compatible and the program SHARE is installed. If SHARE is not installed, only one user will be permitted access to the SELECT/ADD/CHANGE/DELETE Cities screen at a time. If another user attempts to access the data base while the first user has this screen displayed, a SHARE violation/ACCESS DENIED message will appear on the second machine and the program will terminate on the second machine. If SHARE is installed, multiple users or instances may access the SELECT... screen, but only the first one in may Add, Change, or Delete Cities from the database. Subsequent simultaneous entries to the screen will display a message that the file is already locked and that selection of a city is allowed, but that the Add, Change and Delete buttons will be grayed out. Once the first user exits the screen, the lock is cleared for other users.

If there is only one \Windows directory in a multiple user network, there can be only one INI file, which contains the default city and last used options. If each user has his own Windows directory, each user will receive his own copy of the initialization file so that individual defaults will be retained.

Please note that each person on the network who uses Eye On Sunrise must have a separate registration. It is a violation of the license agreement to allow multiple users on a network to access a single registered copy. Site licenses are available at a discounted rate for multi-user access. Please contact Arbor Verde Press for details.


Registration Screen

The first time you run Eye On Sunrise, you will be asked to enter your name for registration purposes. The name you enter will be used to provide a unique serial number key should you decide to register the program. Then, the opening copyright screen will display. If you have a registered version, a copyright screen will display briefly and then load the program.

If you have an unregistered version, several command buttons are available at the opening screen:

The first command button, "I Agree," will take you directly into the program.

The second command button, "Quit," will terminate the program.

The third command button, "Registration Info," will pop up the help file and display information on registering Eye On Sunrise.

The fourth command button, "Change Name," will allow you to change your name prior to completing the program registration form.

The fifth command button, "Print Reg. Form" will prompt you for your mailing address and then print out a form you may send in with your check to register the program and receive your unique serial number.

The sixth command button, "Enter Ser. Number" is used to enter the number you receive from Arbor Verde Press when the program is registered. Once you enter a valid serial number, the opening shareware display screen will be disabled.

The seventh command button, "Supp. Copyrights" will display additional copyright information.


Main Screen

Eye on Sunrise will assume that your computer clock and date are set correctly. All times shown and dates selected are based on this assumption. If your clock and date are not set correctly, you may change them using the Date/Time selection from the Windows Control Panel. Consult your Windows operating manual for details.

If your location observes daylight savings time, it is important that you change your computer clock time to the correct hour when you go on and off daylight savings time. Eye On Sunrise depends on you having your own clock set to your time.

As you select different cities and different options, Eye On Sunrise records your choices and remembers them. Whenever you run the program, it shows the last city you looked at and uses the options you selected in the previous session.

As soon as possible after installing the program, you should be sure to set your location (the "default" location). The program will use this location for some of the time display options. In this file, "your location" and "default location" apply to your selected home town. "Alternate location" or "remote location" refer to any other city you may be reviewing. See the section Selecting A City To Review for instructions.

To close the main form and exit the program, select File-Exit from the pull down menu or double-click the control box in the upper left portion of the screen.

The following sections explain each part of the main screen.

Universal Time

UTC is Universal Coordinated Time and is functionally equivalent to Greenwich Mean Time, the time in Greenwich England (GMT). The UTC time zone represents the number of hours that need to be added to local time to get UTC time. For example, New York City is time zone +5, or Eastern Standard Time. When it is twelve noon in New York, it is 5:00 in the afternoon in Greenwich England. Eye On Sunrise uses only positive UTC time zones, numbered from 0 to 23. For time zones east of Greenwich England, many sources label these as negative time zones. To convert a negative time zone to a positive one, add it to the number 24. For example, the time zone for Paris France is often listed as -1 UTC. Since 24 + (-1) = 23, the Eye On Sunrise time zone should be entered as, and will display as, 23. To convert from a positive time zone to a negative one, subtract 24 from the positive time zone. Since 23 - 24 = -1, the equivalent time zone for +23 is -1.

If you know the equivalent time for any city compared to a known time in another city, you can figure out the time zone code by using the World Clock and Map Display. See that section for more details.

UTC time is used as the official time zone by scientists and in many professions and hobbies such as Ham radio. By using UTC time, there is no confusion about time zones or questions as to what time it really is or whether a zone is on daylight savings time or not. You may display the various times shown in your time zone, the time zone of a particular city, or UTC.


The Calendar

Today's date will automatically be displayed on the calendar when the program loads.. To change dates, simply click your mouse on the new date. To change months or years, click your mouse on the arrows on either side of the month and year heading. As you select different dates, the sun-moon times will be calculated and redisplayed.

The captions for the name of the month and the days of the week will appear in the language selected in the Windows Control Panel under the International section.

Note -- Be aware of the change to daylight savings time. In those areas in which it is observed, it usually runs from the first part of April to the last part of October. This varies somewhat and the dates on which it occurs and whether or not it occurs are controlled by political bodies, not astronomical events. Be sure that the option buttons that select Daylight Savings Time are appropriately checked for the dates you will be checking! See the section Daylight Savings Time for more information.


Sun and Moon Times

The format for the times displayed will be that selected in the Windows Control Panel under the International section. Because this display is controlled by Windows, the times listed may include a seconds display as well as minutes and hours. If this is the case, the seconds portion will always display :00. The times calculated are not precise enough to display the actual seconds and are accurate to within one minute or so.

There are days when the moon does not rise and/or set, and for some locations at high latitudes, there are days when the sun does not rise and/or set (for example, the northernmost cities have several days of darkness in the dead of winter). When this occurs, the time is indicated by **:**.

The sunrise, sunset, moonrise and moonset times are calculated for a 6 foot tall observer and a level horizon. If mountains or hills block the horizon, the time when the sun or moon peaks over them will be slightly later for rise times and slightly earlier for setting times. Similarly, if you are standing on a mountain and the horizon is below level, rise times will be slightly earlier than displayed and setting times slightly later.

If the percent full moon figure has a plus sign in front of it, it means the moon is waxing, that is getting closer to full as the days progress. If the full moon figure has a minus sign in front of it, it means the moon is waning, or getting closer to new as the days progress.

The moon is full not on a given day, but technically at a particular instant in time which may or may not occur during the time the moon is visible at the selected location. For this reason, the percent full figure is never shown at 100% and there may be up to two days when the percent full figure is listed as 99%. This applies to the new moon as well (0% full).

Latitude and Longitude for the provided cities data base have been extracted from various almanacs and geographic atlases. Every effort has been made to insure accuracy, but if the information is critical to you for a particular city, we recommend you double check the figures against your own sources. There is also some disagreement about the exact latitude and longitude for any particular city. Some sources have used the city center; others use an airport which may be out of town. Many of the larger cities extend a couple of minutes or more north-south and east-west, so sunrise, for example, may occur one or two minutes earlier on one side of town than another. The Select/Add/Change/Delete screen allows you to change the latitude and longitude of an existing city in the data base to suit your own purposes.

The box marked "Location Time Zone - UTC +" shows the time zone for the city being displayed.

The box marked "Reported Time Zone - UTC +" shows the time zone in which the sun and moon times are displayed above. You have your choice of displaying the sun and moon times in your time zone, the time zone of the location you are looking at, or UTC time.


Time Zone Displayed

Three option buttons appear in the lower left of the main screen labeled Use Your Time Zone, Use The Location's Time Zone, and Use UTC Time.

If you select Use Your Time Zone, the sun and moon times shown will be relative to your own clock. This is handy for travelers who do not change their watches when they travel. Suppose, for example, you live in Tucson Arizona and will be traveling to New York, NY on December 15. If you select Use Your Time Zone, Sunrise will be listed as 5:13 am which is the time the sun will rise according to your wristwatch if you leave it set to Tucson Time.

If you select Use The Location's Time Zone, the sun and moon times shown will be those that match the clocks at that location. Using the example above, Sunrise will be listed as 7:13 am.

If you select Use UTC Time, the time displayed will be the time sunrise will occur at the location according to the world's atomic clocks.

Regardless of the time zone selected, be sure that the Daylight Savings Time buttons are appropriately checked for the date you are reviewing.

Remember too that if you have Use Your Time Zone selected, locations far to the east of you may actually be reflecting tomorrow's times if they are on tomorrow's side of the international dateline (conversely, if you are in a far east location and the location you are reviewing is on yesterday's side of the international dateline, the times listed will actually be from yesterday). The international date line is represented by the time zone code +- 12.


Daylight Savings Time

Two groups of option buttons are located in the bottom middle and bottom right of the main screen. You may choose standard time or daylight savings time separately for your location and the other location you are reviewing.

If your location observes daylight savings time, you should have your daylight savings time option button checked whenever you are reviewing a date during the period in which daylight savings time occurs. This generally applies to the period between the end of April and the end of October. For example, if the actual date is December 15 and you live in New York City, select the Daylight Savings Option button if you are looking at a date of July 4.

You should also make sure your daylight savings time button is checked appropriately based on today's date when you are viewing the World Clock and Map Display. Remember, the program assumes you have your computer clock set to the correct local time.

If the alternate location you are reviewing observes daylight savings time, be sure to select the daylight savings time option button for the alternate location whenever you are reviewing a date during the period in which daylight savings time occurs.

Eye On Sunrise does not store whether a particular location observes Daylight Savings Time. These things are political and often change. Also, the dates during which Daylight Savings Time are observed vary in different countries, and in many places, some portions of a country or state do make the switch and other portions remain on standard time depending on their exact geographic location.


Current Time Display

At the bottom of the main form is a continuously updated display of your time, the alternate location's time and UTC time. Remember, Eye On Sunrise will assume your computer's clock is set correctly. Be sure to reset your computer's clock when you go on and off Daylight Savings Time. The time displayed for your time will always be whatever your computer's clock says. If you do not have the daylight savings options buttons correctly selected, the times shown for alternate location and UTC may not be correct.


Menu Selections and Button Bar

You may select any other Eye On Sunrise function either by selecting from the drop down menu or by clicking on one of the command buttons at the top of the main form. The following sections explain each option in detail.

Toggle Main and Alternate Selection

Two cities are remembered by the program for immediate access -- your location and another location of your choice.

To switch to your location, either click on the House icon on the button bar or select File-Your Location from the pull down menu.

To switch to the alternate location, either click on the Tropical Island icon or select File-Alternate Location from the pull down menu.

When either choice is selected, the sun and moon times are recalculated and the name of the location appears on the caption bar of the main form.

To change either your default location or to select another alternate location, see the next section, Selecting A City To Review.


Selecting A City To Review

To load the screen that allows you to select a location, or to add, change or delete a location from the cities database, click the Cardfile icon on the button bar or select File-Select/Add/Change/Delete from the pull down menu. A new screen will display.

To select a city, you may:

Start typing a city name into the drop down box at the bottom of the form. The closest match will appear as you continue typing letters into the box.

Scroll through the cities data base using the First/Previous/Next/Last buttons until the location you want is displayed.

Drop down the list box at the bottom right of the form, scroll through it with your mouse or arrow keys and click on the city of your choice.

Once the city you want appears, click the USE button to make it your alternate location, or click the USE AND SAVE AS DEFAULT button to select the city as your home location.

If you want to delete the selected city, click the DELETE button. You will be asked to confirm your deletion. This option permanently deletes a selection from the cities data base.

To add your own selection to the database, click the NEW button. This will activate the spin buttons and clear the screen. Type in the name of the location in the box at the top and use the spin buttons to set the latitude, longitude and time zone. If the time zone is a 30 minute offset (e.g. 14.5 UTC), use the spin button to select the number to the left of the decimal and then check the +30Minutes check box. Time Zones Codes must be entered as a positive number between 0 and 23. See the section Universal Time to convert negative time zones to positive time zones if your source gives a negative number for a Time Zone Code. Make sure you have the North-South and East-West option buttons properly checked. Then, click the SAVE button to save, or CANCEL if you change your mind and don't want to store the new location after all.

The data base that stores the cities is not itself limited in size, but the drop down list box that displays the cities for selection is limited to 32,000 characters. This means that you will be allowed to store between 1,000 and 2,000 locations depending on the total length of the cities' names.

HINT: if you do not know the time zone for your new location, but you have a reference that lists what the time at the location is compared to a known time somewhere else, use the World Clock And Map display to help you figure the time zone code.

If data for a particular location is entered incorrectly or if you wish to change it, first select the location and then click the CHANGE button. This will unlock the spin buttons and text display at the top for editing. When you have finished the changes, click the SAVE button to save your changes, or CANCEL if you change your mind.

If you select USE or USE AND SAVE AS DEFAULT, the screen will close automatically. If you wish to exit without making a selection, click the EXIT button or double-click the control box in the upper left corner of the display.


World Clock And Map

To display a map of the world with continuously updated times for each of the world's time zones, click the world map icon or select File-World Map from the drop down menu.

A map of the world will appear and below it, the current time in each time zone. Your time zone will appear with a white background; the remaining time zones will appear with gray backgrounds. The display is updated every 10 seconds.

There are two spin buttons at the bottom of the display, one for hours and one for minutes. If you activate them, you can set the display so the hours and minutes are set into your time zone display and the corresponding times for the remaining time zones are calculated. You may use this in several different ways:

If you want to know what time it will be somewhere else when it is a certain time in your location, use the spin buttons to enter the time desired into your time zone. The corresponding times in the rest of the world will be displayed.

If you need to know what time it will be at your location when it is a certain time somewhere else, use the spin buttons up and down to set the time for the foreign time zone. The time it will be at your location will then appear in your own white box.

If you want to enter a new city and are not sure of the time zone code but have a reference that lists what time it will be when it is a certain time somewhere else, use the spin buttons to set the time listed for the known location and look at the display for the time given for the foreign location. The box in which that time is found will be the time zone code for the foreign location. Example: A reference you have indicates that when it is 12:00 noon in New York, it will be 2:00 pm in Montevideo, Uruguay. Use the spin buttons to adjust the time in the UTC + 5 box (New York) to 12:00 pm. Look on the display until you find 2:00 pm in the +3 box. The time zone code for Montevideo will be UTC + 3.

Clicking on the RESUME button after adjusting the spin buttons will cause the real time display to re-appear.

To close the map, click on the EXIT button, or double-click the control box at the top right of the screen.


Weather Forecaster

To load the weather forecaster, click on the rain cloud icon on the button bar or select File-Weather Forecaster from the drop down menu.

To read your forecast, click on the appropriate option buttons for wind direction, barometric pressure and barometric tendency. Note that not every combination leads to a specific forecast.

The Weather Forecaster portion of Eye On Sunrise has been extracted from information published by the United States National Weather Service and other sources. It is based on the fact that certain large scale weather patterns are typically associated with observable changes in wind direction and barometric activity. It is most accurate for the eastern 2/3rds of the United States and other locations in the Northern Hemisphere during the fall, winter and spring.

It is not infallible, however, and certain care must be exercised in applying the principles it embodies.

The barometer rises and falls daily as a natural result of sun heating. Do not mistake these small diurnal changes in barometric pressure for genuine changes in direction. It takes a little practice and familiarity with a particular area to know what is normal variation and what is a real shift.

The barometer readings are general guidelines and are strictly applicable at sea level. The pressure is normally lower as you increase elevation, so you should make the appropriate changes at locations above sea level. As a rule of thumb, the barometer readings decrease 1/10 inch for each 100 foot increase in elevation. Note, however, that readings you obtain from weather reports are already corrected to sea level for you. Also, most home barometers can and should be calibrated for elevation. See the instruction manual that comes with your barometer.

The wind directions are those for the large weather fronts that accompany the weather changes. Local topology (like nearby mountains or lakes) can cause eddies and swirls so the direction of the wind at your exact location may not be the true direction of the weather front.

These guidelines are for the most common types of weather systems, but there are many known weather patterns that break the rules on occasion. Even experienced forecasters and meteorologists are wrong occasionally. There are also localized weather patterns that vary from the standard mold.

Nevertheless, the chart is useful and fairly accurate over the long haul if interpreted properly and combined with some common weather sense.


Heat Index, Wind Chill and Dew Point

To load the combination heat index, wind chill and dew point calculator, click on the thermometer icon on the button bar or select File-Heat Index.. from the pull down menu.

Click on your choice of Fahrenheit or Centigrade display. The program will remember your choice the next time you use the calculator. Use the spin buttons to adjust the temperature, humidity/dew point and wind speed and read the heat index in the red box and the wind chill in the blue box. The red and blue boxes will be blank if the selected temperature is outside the range of the calculator. The range of the heat index is from 75 degrees F to 125 degrees F. The range of the wind chill is from -45 degrees F to 35 degrees F with wind speeds from 0 to 45 mph.

To close the form, click on the EXIT button or double-click the control box at the top left of the form. An explanation of Heat Index, Wind Chill and Dew Point follow:

HEAT INDEX. The Heat Index, or Apparent Temperature, is a measure of how hot it really feels when humidity is factored into the actual air temperature. As humidity increases, the ability of the body to rid itself of excess heat through evaporation of perspiration is reduced. By using the Eye On Sunrise Calculator, you can find out how hot it will feel for any combination of actual temperature and humidity within the range of the calculator (approx. 75 degrees Fahrenheit to 125 degrees Fahrenheit).

The Heat Index, as published by the National Weather Service, takes many factors into account and is based on actual biometeorological studies. In fact, there is no simple equation for calculating the heat index. The Eye On Sunrise Heat Index Calculator uses an approximation calculation provided by the National Weather Service that is accurate to within 2 degrees or so over most of the range of the calculator.

Eye On Sunrise allows the calculator to reach temperatures somewhat in excess of printed charts so you can see how drastically the apparent temperature increases at higher temperatures such as those in a closed parked car, but these extreme values may not be as accurate as those toward the middle range of values. When the heat index exceeds 150 degrees, the calculator shows it as "***" because figures higher than this are outside the accurate range of the calculation. If the heat index is below the range of the calculator, the red box is left blank.

One important note -- the heat index assumes a light breeze and shady conditions. Full sun or hot dry winds can raise the heat index by as much as 15 degrees.

WIND CHILL. Wind increases the rate of heat loss from the body. A cold day combined with a stiff wind can be extremely dangerous. The Wind Chill Calculator will display the apparent or felt temperature based on the actual temperature and the wind speed.

There is no exact calculation for Wind Chill as the official table is based on actual observation. The Eye On Sunrise Wind Chill Calculator uses an approximation calculation provided by the National Weather Service that is accurate to within 2 degrees or so over most of the range of the calculator (-45 degrees Fahrenheit to 35 degrees Fahrenheit; wind speeds up to 45 mph).

According to the National Weather Service, winter cold takes more lives than any other natural hazard when accidents caused by bad weather are factored in.

DEW POINT. There are two ways of measuring the amount of moisture in the air. The first is to express it as a percentage of the amount of moisture the air could possibly hold. This is what is referred to as relative humidity. Because warm air can hold more moisture than cool air, a given amount of moisture in the air will cause a lower relative humidity as the temperature increases during the day, even though the actual amount of moisture remains constant. As you cool down the same body of air, the relative humidity increases. When you get it down cool enough, the relative humidity reaches 100% and that is when moisture starts condensing out of the atmosphere in the form of dew or fog. The Dew Point is the temperature at which the relative humidity reaches 100% and is a measure of the actual amount of moisture in the air. If you know the Dew Point and the current temperature, it is possible to calculate the relative humidity. Conversely, if you know the temperature and the relative humidity, it is possible to calculate the dew point.

You can use the dew point calculator and heat index calculator together to estimate the heat index of the projected high for the day if you know the current temperature and either the dew point or the relative humidity.

If you know the dew point, adjust the temperature indicator  to the day's projected high and adjust the humidity/dew point indicator so the correct dew point is displayed. That will calculate what the relative humidity will be at the day's maximum forecast temperature. The program will  display the estimated heat index automatically if it is within the range of the calculator.

If you know the current temperature and relative humidity, first adjust the temperature indicator to the current temperature, and then adjust the humidity/dew point indicator to the current relative humidity. Note the figure given for dew point. Then, follow the steps in the paragraph above.

Eye On The Weather

Tucson based Arbor Verde Press has announced the release and immediate availability of Eye On The Weather, a new software program for personal computers running the Microsoft® Windows operating system.

Increased tourism, widespread migration to the western and sunbelt states and the growing popularity of outdoor related activities such as camping, photography, bird watching, hiking and fishing have made weather and climate an important concern for millions of people. Although short term weather forecasting services are readily available, few resources exist for those desiring information on typical conditions at different times of the year in advance of a planned vacation or relocation.

Eye On The Weather answers this demand with an easy to use software program that summarizes and graphs average and record weather conditions for selected cities and popular recreation areas in an attractive and useful format.

Literally millions of raw National Weather Service readings for temperature, rainfall and snowfall have been analyzed and reduced to compressed station summaries that give a complete picture of the weather across a state or region. Initially available for Arizona (including 33 separate sites statewide at elevations ranging from 206 feet to 8050 feet), Arbor Verde Press will offer additional data sets for other selected states and a special volume of western National Parks and Monuments starting after the fourth quarter of 1993.

Eye On The Weather offers much more than weather data, however. Included is a telephone dialer pre-loaded with numbers of recorded weather announcements from around the nation plus telephone numbers for road conditions, ski reports and other items of interest.

Also included are easy to use calculators programmed to figure the Heat Index, Wind Chill Factor and Dew Point. For amateur weather buffs, a do-it-yourself forecasting program is included and for foreign users, a degrees Fahrenheit to Celsius and inches to centimeters converter is available. A map function conveniently locates any particular weather station selected on an outline map of the state.

Sunrise, sunset, moonrise and moonset times plus percent of full moon are displayed daily and may be calculated months or even years in advance. The times may be reported in any desired time zone.

A particularly useful part of the program is the extensive context sensitive Help file automatically loaded when the program is run. In addition to complete operating instructions, the Help file also provides thorough but non-technical explanations of weather phenomena such as tornadoes, dust devils and lightning; precautions recommended during weather emergencies; first aid instructions for heat stroke and hypothermia; and a complete section on weather proverbs and old-timer weather sayings.

Eye On The Weather should prove invaluable to anyone with an interest in the outdoors and outdoor activities, tourists and winter visitors, those considering relocation, and professionals in the tourism and real estate industries. Eye On The Weather carries a very affordable introductory price tag of $29.95 for the Arizona Edition and may be ordered direct from the distributor, Precise Management Incorporated, at PO Box 5107, Tucson, AZ 83703-0107, USA (plus $3.00 shipping & handling; AZ and TX residents add 5% sales tax). Due to the large data bases involved, Eye On The Weather is being distributed as commercial software only and is not available in Shareware form. Descriptive brochures are available on request at the address above or by calling (602) 577-7700.

Other editions and separately available data sets will be priced similarly, varying slightly depending on the number of data disks.

Program requirements:

•	A 286 personal computer running Microsoft Windows Version 3.1 or higher (386 or higher strongly recommended).

•	Two megabytes of available RAM memory.

•	A mouse or other compatible pointing device.

•	EGA or higher-resolution monitor (VGA or higher strongly recommended).

•	A high-density floppy disk drive and about 3MB of hard disk space for the program. Each state you load will require between 500K and 2MB of additional hard disk space depending on the state and the number of stations it contains. State tables may be loaded to the hard disk for easy and quick access, or read directly from floppy disks to conserve hard disk space.  NOTE: All Arbor Verde Press publications use a "library" of common routines. If you already have another AVP program installed, the additional disk space requirements are actually fairly low -- less than 1MB. Similarly, if you install another AVP program, the disk requirements will be lower than that stated in the documentation.
