Getting More Files Open
Copyright (c) Richard F. Griffin

-------------------------------------------------------------
This unit demonstrates how to increase the number of files that can
be opened in a program.
The program will open all the *.PAS files in the current directory.
The procedure SetFileHandles() will allow the program to open as
many files as needed at the same time, up to the number passed as
the argument (not to exceed 255). This number cannot exceed the
value given in the FILES= command in the AUTOEXEC.BAT file.
New procedures/functions introduced are:
