As several people have suggested, adding MODE=HOME does the trick. I thought it was not necessary since I had specified JOBNAME, but apparently not. John Welke sent me this illuminating private message:
"I saw your question on IBM-MAIN about SLIP IF not working and as I only subscribe to the digest I thought it easier if I reply directly to you. I encountered a very similar problem many years ago and the trick was to include “MODE=HOME” on the SLIP trap. This is alluded to in the reply from Harris Morgenstern from IBM (shown below). Date: Wed, 8 Jun 2022 13:51:49 +0000 From: Harris Morgenstern [email protected] Subject: SLIP IF not working MVS System Commands discusses this: PVTMOD/PVTEP without JOBNAME/ASID and MODE=HOME: This consideration pertains to the PVTMOD and PVTEP parameters when specified in an IF or SBT PER trap for a module that was not loaded with GLOBAL=YES. PVTMOD and PVTEP are used for monitoring execution in modules that reside in private storage. Whenever possible, specify JOBNAME or ASID, and MODE=HOME, when you use PVTMOD or PVTEP in order to avoid performance impact due to PER interrupts occurring within the range of the specified private load module but in another address space. Using this parameter combination communicates the following information: - JOBNAME or ASID tells SLIP to match only when the PER interrupt occurs under the indicated job. - MODE=HOME tells SLIP to match only when the PER interrupt occurs while executing in the home (dispatched) address space. - JOBNAME or ASID in combination with MODE=HOME tells SLIP to set the PER range only when the private module is loaded into storage in the specified address space. If this parameter combination is not specified, SLIP sets the PER range the first time the private module is loaded into storage, regardless of which address space performs the load." So now we know! I am not sure the above extract is in the current version of System Commands; I couldn't find it in the description of the MODE parameter. Thanks to all.

In addition to PVTMOD=, try also specifying MODE=HOME. -- Phoenix Software International Edward E.
