Hi
I've a requirement to create an output dataset with processing date as qualifer which is in the input file.
Currently I use bpxwdyn within the cobol program to dynamically allocate dataset during runtime.
Is there another way to do it from JCL using Rexx? The problem with above is the dataset is cataloged even the job fails with an error, ex s0c7.
Thanks for your time

That is not a problem - you may need the dataset for problem determination. You can have an automatic clean-up by having a housekeeping step as the first step which will delete the dataset if it exists. |

| Nic, I meant problem because the created dataset will be picked up by downstream application online. The failed incomplete dataset will impact the downstream application as well. |

| Then your scheduling is wrong. Downstream jobs requiring that dataset should wait until it is successfully created. That is one of the things that schedulers are for. |

Have a look at the JCL Reference and see what DISP does.
As NicC says, if the JOB has failed, why is anything "downstream" running? |

| If you are on z/OS 2.1 then you can use system symbols in JCL. |

Nic, Bill,
Like I said...it is an Online application which picks up the file not the downstream batch application.

| hm, make it into a 2 step process where step1 will create the data in a temp file and step2 will rename that to the final name if step1 completes rc 0 ? |

When you say the dataset is catalogued we assume you mean a PS dataset.
What are you reading that with, online? |

| Why do you overlook Bill's advise on DISP, it looks like you are confused about what is happening and what do you want actually? |

If you don't want to answer my previous post then please chage it to create a GDG instead of PS file so that online would still be find with earlier GDG ( of cource, if your Business accepts that way) but DISP still needs to be (NEW, CATLG, DELETE) and not (NEW, CATLG, CATLG). |

You did not specify that it was an online program.
What is an online program doing creating a sequential file? Can you not initiate a batch job to create the file when the data is ready and make the downstream dependent on that? |
