I want some information regarding the linkage data. I'm passing parms in COBOL program though the JCL. Will I be able to receive the same parms in the calling program with linkage section though the JCL?
Thanks,
Amsarl |

| Your question is not at all clear. Are you asking if you have a COBOL program calling a program and you want to pass a parameter to the calling program through a JCL parameter, do you need a LINKAGE SECTION? The answer to that is yes. If you're asking about calling a program from within COBOL and passing the JCL parameter to the called program, you must get the parameter in the calling program -- the called program will only have access to the data passed by the calling program. If you're asking something else, please clarify what you want to know. |

If i understand your question, no.
The program named in the jcl can see the jcl parm. To use that parm in some called module, the parm would be passed to the called module with the "CALL mod USING. . .".
If that is not your question, please clarify. |

Hi Robert,

I have main program A which is receiving a data in his linkage section through JCLS parms, B is the subprogram called by A.
My query is that instead of sending the linkage data from A (Received from Jcl parm) into B, directly can i access the parms in jcl in linkage section of my called program B.
But from all your reply i understood that i cant do like that. Correct me if i am wrong?
Thanks,
Amsar |

Instead of
Call B using B-passed-data
use
Call B using A-parm-area B-passed-data.
As long as you keep passing it, it will be there. |

| As CICS Guy says, what you pass to the called program is what it can get to. If you pass the JCL parm, it'll be there. If you don't, you can't get to it. |
