Jcl to compare GDG version creation date with system date

Hi

Currently I am using GDG version created by source system(monthly once) in my monthly job.
I need to have a check whether the latest version avaliable is not the one which is created in last month(reason might be that source system has not created the current month version by the time my job kicks off)
Could anyone help me with JCL to implement the check.

Create a file that contains the last GDG processed.

Use IDCAMS LISTCAT to get current generations of the GDG.
Use a program to parse the LISTCAT output to find the latest generation.

Use a program to compare the generation in the file against the output of the LISTCAT parse to see if they're equal. If not, write the latest generation to the file and proceed.

What you're wanting to do requires at least one program -- it cannot be done purely with JCL, which does nothing but execute programs anyway.

And also, please use the correct terminology. Versions and Generations are both valid terms when dealing with GDS.

If YOU do not understand the correct terminology, how the hell do you expect us to really know what you mean.

Please get it right next time !!!!!!!!!!!!!!!!!!!!!

Hi I agree with Robert's processing steps, and I think these can be done by 'pure batch', if icetool is defined as part of it. It can do the find string job as well as matching.
