Update 1.1.0:
=============    

     This version has been enhanced so that the current system time and date

is currently displayed for your convenience.


Update 1.2.0:
=============    

     This version corrects a cosmetic defect and upgrades the software to dis-

play the title page and Periodic table in VGA, EGA and CGA mode.


Update 1.3.0
=============

     This version corrects a bug that caused the mis-calculation of the CFM

for both Heating and cooling modes.  It also is the first release with the

new ZIP code for Enchanted Tree Software.


Update 2.0.0
=============

     We have listened to our critics and users and have incorporated the most

accepted method of analysis.  The manual J is used for data input factors and

for calculation methods.  This will result in a more acceptable method of 

analysis.  The printout feature found only with the registered version also

lists the construction features and heat loss/gain factors as well as the

BTU's lost/gained through area in the structure.

+-----------------------------------------------------------------------------+

     This version of BTU Analysis is setup for the Shareware market.  We

believe that you should try before you buy.  Therefore we are issuing this

version of BTU Analysis.

     This software is NOT FREE!!  You are expected to pay for it if you wish to

use it.  The fees collected from this program will be used to help develop

other useful and user-friendly programs.

     We strongly advise, if you use it.  Pay for it!

+-----------------------------------------------------------------------------+

    The registration fee for BTU Analysis is $99.95 plus $5.00 shipping and

handling for a total of $104.95

    Registered users will receive the registered version of BTU Analysis.

This version has utility features incorporated into it that allows three

types of hardcopy reporting of results, automated data file backups, and

user data file saves.  Registered users are the only users that will

receive update notices, and software support.

+-----------------------------------------------------------------------------+

     Enough of that,  this program is designed to simplify the process of

sizing heating and cooling units that are to be used in commercial and res-

idential applications.

     If you have ever tried to calculate the heat loss or gain of a structure

before you know that it is very difficult.  This program asks for the par-

ameters necessary for the calculations and then performs the calculations for

you.

     The program will translate the cooling into Tons as well as BTU's and will

give the cfm necessary for proper cooling or heating of the area analyzed.

     The program is chocked full of help screens and features that make it a

pleasure to operate.

+-----------------------------------------------------------------------------+

     Floppy disk users may have to install a CONFIG.SYS file with some buffers 

and files statements for the program to load and run successfully.

Example CONFIG.SYS file
FILES = 10
BUFFERS = 10

                                     Enjoy!!
