You might use a fairly unobvious approach (and a little slow), but 
much more compatible than using the DOS EXEC function:

call your program from a batch file.  Call this batch file Menu and
make it read: 

	my_menu.exe
	menu_go.bat

Then your program has to write menu_go.bat to read something like:

	c:
	cd \a\direct.ory
	aprogram.exe
	.
	.
	.
	cd \menu
	menu.bat

This batch file will be made differently depending on the selection
from the menu.

One noteworthy advantage for this is that it use exactly 0k memory,
and the program will be being called from DOS's COMMAND.COM so there
is approximately zero oppurtunity for compatiblity confilcts.
