E&OE. This code is supplied 'as is' with no support.
This code will compile with Turbo Pascal 7.0 on FreeDOS in a VirtualBOX VM, provided that the TP7 CRT patch is installed;
if not, the program will stop immediately with a Runtime 200 error - see
http://www.filewatcher.com/m/bp7patch.zip.62550-0.html
The code will also compile with TP7 running in DOSBOX on Windows 10. See
http://techapple.net/2014/04/turbo-pascal-7-windows-7-windows-8-8-132bit-64bit-fullscreen-single-installer/
If you want to compile this code, you will also need to download and compile the custom (TPU) units: disk2, screen, win,
chrono and chartool. The win unit files may need to be grabbed from TP6.
