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.
