Yes, click the "IBM Manuals" button at the top of any page, then find the JCL reference manual, and read it.
If you then have problems after reading the manual, please feel free to post your question clearly stating what the problem is. |

Thanks..I went through the manuals even before posting this question.
I just have a small doubt, suppose you want to override a symbolic parameter that is declared in the proc through the jcl.
eg. In the proc HM50099P
//HM50099P PROC PGM1='HM4020',
// PGM2='HM5050',
I want to override PGM1 and comment PGM2 through the jcl.
Could you let me know if this is possible. |

Without seeing the internals of the PROC how can we help.
This is something that you could try yourself, just create your own instream procedure to ensure that whatever you do will not affect any production datasets, and see what happens.
I don't wish to appear brash, but this is a HELP forum rather than a reference library for things that can so easily be tried and tested by yourself. |

Expat,
with TYPRUN=SCAN any JCL can be tested, production or not. |

True, but one exhibit from the black museum of experience was when I submitted a job TYPRUN=SCAN and inadvertantly erased the comma before the statement, so the job ran ................. caused all sorts of grief at the time. Hence the advice to use a test proc for trial / testing / learning purposes. |

As is common in this age of "agile development", the requirements were not fully considered or specified at first. Tell us everything else that you want to do in this job -- run STEP2 five times and skip the rest of the steps, perhaps? -- and then you might get a meaningful answer. |

| To be honest, I think the JCL Reference Guide is quite clear about what is and is not possible in a PROC override. |

eg. In the proc HM50099P
| Code: |
//HM50099P PROC PGM1='HM4020',
// PGM2='HM5050',
|
change the code in your PROC as below
eg. In the proc HM50099P
//HM50099P PROC PGM1=&PGM1,
// PGM2=&PGM2,
In you runjcl where you are invoking the PROC HM50099P, substitute the values for PGM1 and PGM2 to whichever you want at run time.
Runjcl:
// EXEC HM50099P,PGM1='HM4020',PGM2='HM5050'
