╔════════════════╗
║ SYSTEM FLAGS ║
╚════════════════╝
This option demonstrates a pair of assembler routines,
GETFLAG and SETFLAG, which are used to set or get the
current status of locations in the Intra-Application
Communications Area, a 16-byte block of RAM reserved,
by DOS, for signalling between applications programs.
These flags retain their settings, even when a program
terminates and so provide a limited means of parameter
passing for stand-alone QuickBASIC programs, compiled
with the /O switch.
