ISPVDTRC System Option: z/OS

Tracing means that, as each SAS variable is identified to ISPF with the SAS VDEFINE user exit, its name, its VDEFINE length, and any nonzero ISPF return codes are written to the SAS log.

If NOISPVDTRC is in effect, then no information is written to the SAS log when a SAS variable is identified to ISPF via VDEFINE. The NOISPVDTRC setting is useful when many variables are defined with one service request because SAS actually issues multiple VDEFINE requests (one for each variable).

To display the current settings of your ISPF options, use PROC OPTIONS GROUP=ISPF.
