To run the ISPF Configuration utility using a REXX Exec, the ISPF data sets for the new release must be cataloged on the system you are using to run the utility. If the system you are using to run the utility does not have the required level of HLASM or SMP/E, you can do one of two things. You must either use STEPLIB DD statements in your logon procedure to access HLASM in the target system's SASMMOD1 data set, and SMPE in the target system's SYS1.MIGLIB data set, or catalog the HLASM and SMP/E data sets on the system you are using to run the utility.

To run the utility using a REXX Exec, follow these steps.

1. Copy member ISPFCU from the SISPSAMP library for the new release to a library that is in your normal SYSEXEC or SYSPROC concatenation. You can rename it if you want to, but avoid names that start with the characters "ISP".
2. Modify the data set names in the exec as indicated in the comments. Use fully qualified data set names.
3. If the required level of HLASM is in LPA or LNKLST, or in the STEPLIB of the TSO logon procedure that you will be using then set the value for asm_load to null (''). If you want to access the required level of HLASM through this exec the data set must be cataloged on your running system.
4. If the required level of SMP/E is in LPA or LNKLST, or in the STEPLIB of the logon procedure that you will be using, then set the value for gim_load to null (''). If you want to access the required level of SMP/E through this exec the data set must be cataloged on your running system.
5. The default names for the ISPF libraries are supplied. They must be cataloged on your running system. Change them as needed.
6. Logon to TSO.
7. Run the exec from TSO Ready. ISPF for the new release will start.
8. Enter the command TSO ISPCCONF to start the ISPF Configuration utility.
