GR.EXE displays two-dimensional random figures on the display
continuously. To exit the program, press the ENTER key (actually, most
any key will do).
The program displays figures from six basic schemes. Within each
scheme the number of points is random. The number of colors is also
random, and some of the figures rotate the color palette cyclically to
simulate rotation.
GR.EXE was developed to exploit the VGA's color palette, but it will also
run on an EGA with reduced color selection, and on a CGA in black and
white with somewhat sub-standard resolution.
A fast machine (12 MHz or better) is recommended. Performance is
almost unbearable on an XT-class machine. An 80x87 co-processor will
help.
The source is included. It was compiled with the Microsoft C version 5.1
compiler using the small model. The graphics library must have been
included when the libraries were built. No special compiler options are
required, but /Ox is recommended.
