Use JCL IFTHEN to test for previous JCL CONDs and let step two run if conditions are met.
You will find more than one sample how to test for empty DSNs. |

And in case you don't know how to check for an empty dataset, here is one method using SORT (well ICETOOL to be precise):
| Code: |
//* COUNT .. EMPTY|NOTEMPTY -> RC 12 IF CONDITION IS MET
//C1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//DD1 DD DISP=SHR,DSN=dataset
//TOOLIN DD *
COUNT FROM(DD1) EMPTY |

| Code: |
//METHOD#1 EXEC PGM=IDCAMS <* RC4 | RC0
//IDD DD DISP=OLD,DSN=..
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
PRINT IFILE(IDD) COUNT(1)

Lines to code should be at a very minimal level for such a task. |

Many ways to do get the same thing , 1-2 lines extra shouldn’t be a problem but at least one would know the way.
Setting up RC-12 may not be a good option as it may considered as abend in scheduling but up to RC - 4 is mostly acceptable code set up for any job but if not then TS needs to make that additional change to allow RC-4 acceptable in scheduling. |
