JDBP>> Actually, the more widely accepted terminology (i.e. everything
 JDBP>> other than the IDE for Borland C++ for OS/2 (-:) is "Not Window
 JDBP>> Compatible", "Window Compatible", and "PM".

 JDBP>> Or, alternatively, "FULLSCREEN",
"PMCOMPATIBLE", and "PM".

 MR> VACPP calls the types None (program determines itself what mode to run
 MR> in),  Window (VIO), PM, or Full Screen.

Then VAC++ is mistaken.  If the type is "None", it is the *parent
process* that determines what mode to run in, via parameters to DosExecPgm
or DosStartSession, rather than the program that is being executed.

After all, by the time that the program has started execution, the session
that it is running in has already been determined.
