Roll-In a Generation Data Set: Example 2

In this example, the ALTER command is used with the ROLLIN keyword to roll-in a generation data set (GDS) that is currently in the deferred roll-in state.
//ALTER    JOB  ...
//STEP1    EXEC PGM=IDCAMS
//SYSPRINT DD   SYSOUT=A
//SYSIN    DD   *
     ALTER -
           DATA.G0001V05 -
           ROLLIN
/*

The ALTER command rolls the SMS-managed generation data set, DATA.G0001V05, into the GDG base.
