How to know GDG base properties through REXX code; Of course we can view the GDG limit thru File-aid 3.2 option But need to list the properties on the fly and may be used in consecutive program/module. Hope made you clear and waiting for response! (Do let me know if any other information is required?)
One caveate to the above suggestion... If you only want GDG entries you may need to consider removing the keyword ALL on the LISTCAT ENTRY('XXX') ALL line. I believe the ALL word will list GDG & Non-GDG datasets that happen to match the catalog entry name.
