Actually you can use a single BPXWDYN command:
cc=BpxWdyn('alloc da(what.ever) shr rtddn(ddn)')
will return the generated ddname in var 'ddn' if cc=0.
Then you can reuse that ddname i.e.
cc=BpxWdyn('alloc da(what.ever.b) shr dd('ddn') reuse') |

It's been a while and I don't have access to the program at the moment. But I've done this before. Make sure you check the RC of bpxwdyn. You can free the ddname and reuse or use another if you want.
If I remember correctly, the process we had ran frequently so we didn't mind if a dataset was skipped until the next run. |

Using such things as dynamic dataset allocation is not needed in 99% of the cases where it has appeared. Especially when the author of this solution does not understand the fundumentals of dataset maintenance under zOS. This approach may demonstrate a pseudo-expert level of the developer to his manager (who in turn has not a minor idea about such issues).
In zOS the same things almost always can be implemented in a simple way, without any sophisticated operations. |
