Return codes

These return codes are possible:

 0
Normal completion.
 8
At least one variable not found.
20
Severe error.
Note:
  1. ISPF processes the entire name list even if it cannot find one or more of the variable names in the list.
  2. With BOTH specified, a 0 return code indicates that ISPF found and removed the variable from the profile and/or the shared pool. A return code of 8 indicates that ISPF did not find or remove the variable from either the profile or the shared pool.
  3. Be careful not to erase variables that provide functions for you during the ISPF session. For example, if you erase function key variables (ZPF01-ZPF24) and do not subsequently specify them, the keys become inoperative.
