Sorry for the fuss I generated. The workaround I referred to is nothing more than an SDSF 'filter' so as to ignore any APPC output. We could not live long or well without APPC functions.
The workaround was suggested by SDSF Level 2. It assumes that you're running the SDSF user exit ISFUSER . We added the following line way up at the front after label INITCK as the first instruction on the first call: NI UPRSFLG2,X'FF'-UPRAPPC *TEMP* TURN OFF APPC DISP This resolved the problem, but of course we can't look at APPC process output. APPC itself works perfectly fine. . .

If "system-wide", that implies we'll have to re-work our connectivity between Rational Developer for System z (RDz) and z/OS from APPC to the SCLM interface, and we've not heretofore done anything with SCLM. -jc- ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
