	OK,OK,OK... I finally found something in TP 6.0 that I couldn't
figure out.  Supposedly anything you execute from a DOS prompt should
execute the same from an Exec() call, so long as no direct video memory
calls are made...  Well, I want to suppress output of a program that
does not use direct video memory, specificly, UNZIP.EXE .  Now the weird
part.  Typing:

	UNZIP FOO.ZIP c:\FOODIR > c:nul

from the DOS prompt works like a champ.  But if you use Exec() from the
DOS unit, and set the parameters like so:

	Exec('UNZIP.EXE','FOO.ZIP c:\FOODIR > c:nul');

and the output is no longer redirected to nul.  It appears on the screen,
and I assure you it isn't a pretty site in the middle of a TVision program.

Any ideas out there ?

Cheers!, and TIA.
