Use of dynalloc to retrieve DD name of a dataset.

Hello,

I need help in retrieving DD name given the dataset name. I read it somewhere that this can be done using DYNALLOC.
Can somebody please tell me how to do this?

Regards

quote where You have read it , please, it might be interesting to know ...
using DYNALLOC You can find the DSNAME from the DDNAME ( not the other way around )

When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort

You are probably referring to the information retrieval function of dynamic allocation. You use the DINDSNAM key to specify the dataset name and the DINRTDDN key to get the matching DD name.

Dynamic allocation is documented fairly well in MVS Authorized Assembler Services Guide for your release. 99% of dynamic allocation can be done by ordinary programs, no authorization is required.
