Hi All,
I've one requirement like based on no.of records in file, i need to execute next step that many times.
For Ex: if my file has 2 records, then next step should execute two times. if it has one then it should execute only 1 time.
Please let me know how we can achieve this scenario?
Thanks in Advance. |

| You can't, you will need a program to do that. |

| No, I mean a program, whatever you prefer - Asembler, COBOL, PL/I, REXX..... |

Thanks Willy Jensen.
Could you please give me outline how we can implement this logic in COBOL. |

| REXX would seem the logical choice, been there, done that when a regression testing job became so large that it exceeded the very hard limit of 255 steps in a job. The job now has a single step running a REXX exec that loops around, and gets its parameters from the name(!) of a JCL file, the job is submitted by an edit macro that dynamically changes this dsname. |

You can do it by means of an instream proc.
You just need to pass the parameters to the instream proc by means of an include call (I have done so a few times).
Using sort is a good way to build the include. |

I have used a REXX EXEC which reads each record, in this case it was about 80 bytes, and passed it as a parameter into a program called by REXX.
So for every record read the program was invoked. |
