This worked for me:

CVT      = C2d(Storage(10,4))
CVTDFA   = C2d(Storage(D2x(CVT + 1216),4))   /* cvt + 4c0 */
DFAMGEN  = C2D(storage(d2x(cvtdfa + 76),4))  /* dfa + 4c */
say 'Maxgen Limit:' dfamgen

Thank you

Indeed, that worked for me, thumbs up!

Please have a look at APAR OA43951 and the corresponding solution:

> Add a new field to the DFA DFAMAXGN which contains the maximum number 
> of generations this system supports.

With this information it should be possible to access the field in the DFA from 
REXX.

HTH.

Subject: PDSE V2 MaxGen Limit Query

Is there a way to query the current MAXGENS_LIMIT from the SMS configuration in 
either REXX or ISPF?

I'm looking for a way to prevent a user from specifying a larger maxgen than is 
allowed in a dialog I'm working on.

Thanks
