Hi,
Is "WHATIF" a TSO command. I encountered the following code in REXX.
| Code: |
"whatif file(sysprint) allocated"
if rc\=0 then
"alloc fi(sysprint) da(*)" |
But I can't find any info on this anywhere. Google shows an entry from CBTtape that says in comment : Using WHATIF TSO command.
Nothing in TSO_E Command Reference or REXX manual.
Appreciate much for any information on this or direction to any manual.
Regards. |
