System REXX and SDSF

If you invoke SDSF's REXX using System REXX, you need to be aware of the following:

• You must set up the ISFJESNAME variable to identify the JES2 subsystem, or the ISFJES3NAME variable to identify the JES3 subsystem.
• You must be authorized to invoke SDSF functions from REXX, as described in Security and REXX.
