To purge a PRIV file, try this:
 
:FILE T=$NULL
:STORE privfilename;*t;SHOW;PURGE
 
This works on 5.0. For 4.0 or earlier, I believe you cannot use a NULL file
equation for the tape. It should work if you use a real (or is it reel)
tape.
 
In either case, you will need the appropriate capability to store PRIV
files (i.e. OP or PM).
 
Alternatively, you can run FSCHECK.MPEXL.TELESUP and use the PURGEFILE
command.
 
Hope this helps.
