	Hello,
			can anyone explain how to find out the name of a program under
DOS 3+ (i.e. how does C set argv[0]). I know it isn't possible for earlier
version of DOS, and I have actually looked at the Turbo-C startup code, but it
doesn't seem to make much sense.  Turbo-C seems to look beyond the end of the 
environment block, but I can't find anything there.  What I actually want to
do is to find out the name of a program, given it's PSP address.

	thanks
