Use these steps to customize your ISPCMDS command table:

1. Copy the ISPCMDS into a data set concatenated before the '*.SISPTENU' data set in the ISPTLIB DD statement.
   • Name the new member using a unique prefix of up to 4 characters, for example: RSMCMDS or MOD1CMDS.
   • Allocate the copied-to data set to the ISPTABL DD card. You can use this CLIST to do a LIBDEF against ISPTABL if you have a ISPTABL DD allocated:

     PROC 0
     ISPEXEC LIBDEF ISPTABL DATASET ID(the_dataset_name)
     WRITE &LASTCC
     END

     If your logon procedure does not allocate an ISPTABL DD card:

     PROC 0
     ALLOC F(ISPTABL) DA(the_dataset_name)
     END

2. Using option 3.9, customize this member with your new commands.
   • Option 3.9 will search the ISPTLIB DD for this member.
   • Option 3.9 will save (UPDATE) this customized member to the output data set pointed to by ISPTABL.
3. After you have customized this member, you can use option 3.1 or 3.4 member list to rename this member to ISPCMDS.
4. Exit ISPF.
   • This will nullify the LIBDEF on ISPTABL.
5. Re-invoke ISPF.
   • When ISPF searches the ISPTLIB DD concatenation, your customized ISPCMDS will be found first.
