Re: Invoking IFASMFDP utility via CALL, LINK, ATTACH ?
Supportability had definitely crossed my mind, so the clarification is both timely and appreciated.

Re: Invoking IFASMFDP utility via CALL, LINK, ATTACH ?
Your post reminded me of a program I wrote that would first check and set a flag as to whether it was running from TSO CP, JOB, or STC. The input parms would be different for TSO of course, and I think the JOB/STC difference was so I'd know to put the output in SYSPRINT or a WTO. Kind of nice to have one program for all 3 environments this particular function required, I thought at the time.

The IBM recommended way to run IFASMFDP is via the IEFU29 exit https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ieae400/ieae40040.htm Joe On Wed, Dec 2, 2020 at 1:25 AM Mike Hochee wrote: > Wondering if anyone has attempted to invoke the SMF IFASMFDP utility > (handles dumping and clearing of SMF data set logs, digital signature > validation, etc.) via program invocation using CALL, LINK, or ATTACH?

Re: Invoking IFASMFDP utility via CALL, LINK, ATTACH ?
I've seen messages about programs that won't work properly if you LINK to them; I consider that bad form, just as I consider reentrant but not refreshable to be bad form. Fortunately, IFASMFDP is not such an offender. -- Shmuel (Seymour J.)

Of course. Do it all the time. Look in the CBT tape for program SMFDUMP.

Re: Invoking IFASMFDP utility via CALL, LINK, ATTACH ?
In general, you can invoke any utility, but some require that you be APF authorized. In the basic form, R1 points to a one-word PLIST with the VL (high bet) set, and the single parameter contains a halfword length followed by a parameter string. Most utilities document and support additional parameters; if the documentation doesn't show them then they don't exist or aren't for custome use. -- Shmuel (Seymour J.)
