Lionel isfreset("all") will drop all SDSF special variables. It won't drop any column stems.
However, we are not sure if dropping a variable always releases the storage. We have seen cases where REXX just marks the SVB available but the storage is still allocated.

Dyck Sent: Wednesday, September 6, 2023 3:39 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: SDSF REXX Question EXTERNAL EMAIL After using the SDSF REXX API and issuing the "rc = isfcalls('off')" is there a way to release/free the storage that the various calls to the API have allocated. I know I can do a "drop isfulog." But is there a general way? TIA Lionel B.
