Trevor, Thanks, I got the Launch command to work. The syntax that you provided in this post actually did not work, but in another post you provided: Launch "C:\WINDOWS\system32\cmd.exe" "/c c:\test.bat" I successfully got the ISM to launch the BAT file, and then I put the following command in the BAT file: call "C:\PerlFileName.pl" That worked. It's strange that I can't get the Launch command to execute the PL file directly, but I don't mind living with strange work arounds. Thanks! Jose
