Commonly used single job step command sequences

A sequence of commands commonly used in a single job step includes DELETE-DEFINE-REPRO or DELETE-DEFINE-BLDINDEX.

• You can specify either a data definition (DD) name or a data set name with these commands.
• When you refer to a DD name, allocation occurs at job step initiation. The allocation can result in a job failure, if a command such as REPRO follows a DELETE-DEFINE sequence that changes the location (volser) of the data set. (Such failures can occur with either SMS-managed data sets or non-SMS-managed data sets.)
