'ANSI2BAS v3.1 was written by Aaron Lapikas of BCData Inc.  This program is
'designed to make the annoying job of creating graphical screens in screen
'mode 0 much easier.  This program is in public domain, and no fee is
'required to use it.  You can use it wherever you want, just maybe give me a
'little credit, like mentioning my name or something like that.  :)

'To use the program, either complile it into an EXE, or modify the COMMAND$.
'If the program is started with no parameters, then the help screen is
'displayed.  I hope that you find this program helpful, and please, give me
'any comments about this program and let me know of any bugs (if there are
'any <gasp>).
