Dynamic Access I/p Dataset whose name as Timestamp value

Hi,
I have a monthly Audit file whose naming convention is like

superk

Well, let's think this process out a bit. First of all, how is the job and/or program going to know what values to use for the variable data:

AUDIT.Yyyyy.Mmm.Ddd

Or, to consider, how is the actual dataset name going to be conveyed to the job and/or program? Are you running some sort of step where you LISTCAT the high-level qualifier to determine the rest of the dataset name?

Hi SuperK and Dick,

Thanfully,The requirements have changed a bit
I will explain the requirement......
A dataset will be created in the UNIX enviroment and through shell script,
it will be exported to Mainframe....The name of this dataset is fixed,
say,AUDIT.BATCH.FILE
This dataset shall contain a file name with names such as AUDIT.Y2008.M05.D02 which will change every month accordingly.

My requirement is to read the first file and extract the file name it contains within......Then use this second file as input to my programs.

Could you please suggest me a way to do this?

The best way, in my opinion, from a Production Support point-of-view?

Make sure that 'AUDIT.BATCH.FILE' is a PDS and that a constant member, let's say AUDIT, is used.

AUDIT should contain either:

A. A valid SET statement, i.e. // SET FILENAME=AUDIT.Y2008.M05.D02

or

B. A valid DD statement, i.e. //INPUT DD DSN=AUDIT.Y2008.M05.D02,DISP=SHR

and then INCLUDE the member AUDIT in your job at an appropriate location.

Otherwise, there's dynamic allocation from the program, copying the variable dataset name to a constant name, revamping the process entirely, creating dynamic JCL, etc., blah, blah, blah, anyone of which have been discussed here already.

Hi Kevin ,

I just got confirmed from the UNIX team....the 'AUDIT.BATCH.FILE' will be a simple PS and it shall contain the file name AUDIT.Y2008.M05.D02 as a single record in it.

I have to pick up this record and place it as an input file to my program....I just saw your previous post in http://www.ibmmainframes.com/about25906.html
But I guess you were referring to PDS which is not my case over here.

Could you please advise any other alternatives ?

I suppose the next best thing might be to copy the dataset to a temp dataset and use the temp dataset for the processing:

Hi Kevin,

Thanks a lot .... your logic worked perfectly fine.
Just needed to know why is this the "Next" best thing and not the best

Thanks once again for your Inputs,
Puspojit
