Sorry about this, but *** CAUTION ***

With the syntax you provided, you will create a file called null in the same directory you execute this in. Otherwise, users may get errors when excuting commands.

Try this instead...

code:

---

shell "%comspec% /c pgp.exe > nul" 

---

If that does not work, try looking at the Help for this program i.e. PGP.EXE /?. Usually programs like Windows Installers and such have hidden switches to suppress them like 290700usam.exe -s.

HTH,
