To put it briefly: SYS$CHECK_ACCESS and SYS$CHKPRO (spelling?).  A
brief summary of these is available through the on-line help:
	$ help sys $ch

Programming these the first time can be a pain to do, since you have to 
set up the data structures in whatever your language of habit is.  After
that, it's cookbook.
