Last night, I posted a note about problems with "which" not finding
files in the current directory:

	I got an e-mail message shortly after posting from Brendan (at sgi) 
confirming that which worked properly for him, so I dug deeper. 

	Which is a shell script (/usr/bsd/which) and SGI has added 
optional args including -f (but not -x) which is the "fast" version and 
does not source ~/.cshrc. Using this option, which did find the local prog. 
So, that meant that it was probably a problem with my very own .cshrc file.  
 
	I found that I was unconditionaly setting my prompt which everyone 
knows is not a "good thing" and can interfere with all kinds of programs 
and scripts. After I fixed my .cshrc not only did which work right, but 
M-x compile (in emacs) started working (the grand total of progress for
yesterday (;-)).

	This morning, Vern (at sgi) posted a note similar to Brendan's mail 
and I got an email message from Brent (at NASA) all confirming that which 
worked for them. 

	To all who replied, thanks.

Dale
