Ah, the joys of POSIX-land.

I'm trying to purge a file which was created by MANAGER.SYS in another
account.  After MANAGER.SYS BUILDs the file, writes data to the file,
"chown" the file, and "chmod" the file, the file is available for various
applications to read.  Or at least that is the idea.  I've run one test,
and I've found a snag.

The snag is that I need to "rm" the file.  Unfortunately, "rm" won't
work.  The really odd part is that "PURGE" will work (see below).  Anyone
run into this quirk before?  Anyone know WHY this happens?

John
