Hi

I need to know whether a previous gdg generation exist or not using relative generation number for example test.gdgdatasrt(-4) ,

//JS10 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
LISTCAT LEVEL('TEST.GDG.DATASET(-4)')
/*

I am receiving the message as "(' DOES NOT ADHERE TO RESTRICTIONS

Thanks for your help in advance

Regards
Sumit

Hi

I searched another post
www.ibmmainframes.com/about48158.html
and If i have understood correctly we cannot use relative parameter.

It would be great if we have some other aternative preferably JCL

Thanks
Sumit

Why not use LISTCAT LEVEL(TEST.GDG.DATASET), put the IDCAMS output into a data set, and scan that data set for what you want to know?

Another approach is BPXWDYN:
Code:
/* rexx  */                                                     
  x = BPXWDYN("ALLOC DD(QQQ) DA('xxxx.yyyyyy.testGDG(-4)') " ,
      "SHR REUSE GDGNT")                                       
  say x                                                         
  DO I = 1 TO S99MSG.0                                         
    SAY "message = " S99MSG.I                                   
  END                                                           

If the allocation fails, then the data set is not in the catalog (see S99MSG.i to be sure).
