I understand the module above is used to allocate datasets on the fly without having to change JCL’s.
My question is, is there something that can check if a dataset has already been allocated before continuing to the module above ?
Thanks for the help in advance.
For this you can also use USR2010N. This is my experience with this routine:
If you try with ALC-DISP1 := ‘OLD’
VALUE H’1708’ /* if dataset does not exist
VALUE H’0410’ /* if alloction already exists
Hope this helps.
Sorry, typo - this should of course be “USR2021N”.
Thanks I thought as much about the typo.
Could this also work if we are trying to see if VSAM dataset is available and if not to then use the same USR2021N ?
Thanks again for the assistance
Sorry, but I’ve no experience using this against VSAM files.
