Yeah. And, IIRC, the "dynamic STEPLIB" facility would basically schedule an IRB onto the initiator TCB. This would do a STATUS STOP on all the other TCBs in the address space. Then find the DCB for the STEPLIB by chasing chains. It would CLOSE that DCB, reallocate STEPLIB, OPEN the DCB again, do a STATUS START, then exit. That never gave me any "warm fuzzies". And, horribly, could convert the STEPLIB concatenation from APF authorized to not APF authorized. <burr/> -- There is nothing more pleasant than traveling and meeting new people!
