	I have just solved a difficulty with MWC that I thought was going to
drive me nuts and I thought I'd share it with the net to possibly reduce
madness around the world.  
	What would happen was that I'd write a program and compile it without
error or complaint, but when I'd run it, the shell loved it so much that it 
would run the program multiple times *without my doing anything*.  It would 
finally terminate (generally after two runs) with the message "<program>.prg: 
no more files" (where <program> was my program name).
	Well, what the problem turned out to be is that if you use Fsetdta() in
your program, the shell goes bonkers.  What you have to do is use Fgetdta()
first to get the old dta address, and when you're done use Fsetdta() to restore
the old dta address.  The shell should do this for you but it doesn't.  Now you
know.
	I'm using v1.1 and have ordered v2.0 .   Maybe v2.0 fixes this.  If it
doesn't, Mark Williams Co. will hear about it.
