Not sure why this initially went off-List.

Maybe I'm crazy but I would try it and find out which CPF message I got. :-)

As a matter of fact, a few minutes after I broadcast my question, I hit on a simple way to do exactly that: I made a copy of the CL program in question (it's a front-end for doing a QShell "rm -r"; I call it DELTREE, and the display file consists entirely of a confirmation screen for the specified path), ripping out the QShell call, and tried it in a batch job.

It crashed with a CPF4103, "Device *REQUESTER not found while opening file DELTREE in library MERCURY."

And no, Larry, you're not crazy, and neither am I. Maybe the author of the CL manual and/or the helptext was a bit nuts, for having not documenting what Mr. Dow pointed out about having to direct it to a device.

(A couple of decades ago, I found out about acquiring devices, and wrote a test program to do just that; I don't think I ever did find a practical use for it.)
