C Purpose:                                                             C
C                                                                      C
C	This program plots data onto a custom user defined screen and  C
C	window using standard Amiga functions from AC/FORTRAN V2.3.    C
C	The plot and screen/window definitions along with the (X,Y)    C
C	data pairs are read in from a disk file.  In this revision,    C
C	the disk file name is input through the command line           C
C	interface.  The package supports linear, log-log, and          C
C	semi-log axis plots.  The data can be plotted with lines,      C
C	symbols, or lines and symbols.  As of now, all plots on one    C
C	screen  must be the same.  See the examples on the              C
C	distribution disk on exactly how to set up your data file.     C
C	Preambles are included for the three axis types; however,      C
C	the other options are what I use most often, which maybe       C
C	the exact opposite of what you need.                           C
C                                                                      C
C	Many "extras" have been included:                              C
C                                                                      C
C	* Automatic axis size determination with some extra room       C
C	* Border between the data and the axis                         C
C	* Ability to access the screen depth gadget                    C
C	* User defined Screen and Window dimensions                    C
C	* Automatic value labeling on both axis                        C
C	* User defined axis labels and plot title                      C
C	* All border values are user defined                           C
C	* Draws the coordinate axis on the graph                       C
C                                                                      C
C	Many "extras" will be include soon (see wish list).  Hopefully C
C	another revision will be out before Jan. 1 1990!! (I also      C
C	have to get my Master's thesis approved by then, so...).       C
C                                                                      C
C	This release is the basis to work from.  It is not intended    C
C	to be a final release.  Please, if you have any comments,      C
C	complaints, bugs, code, etc..., write me!!  Thanks.            C
C                                                                      C
C	Also, I am not too sure about what must be done to release     C
C	this program to the general public?  AC/FORTRAN runtime        C
C	library package problems.  However, I do know for a fact that  C
C	using any or all of this program in a for-profit package will  C
C	get you a visit from me and my BIG brother.  If you would like C
C	to use any or all of this package in a public domain type      C
C	program, remember to place somewhere in your program who       C
C	actually sweated out the code!!!  Thanks                       C
