I'm trying to understand how to use the catalog fields:
COMUDSIZ
UDATASIZ
COMPIND
VVRNFLGS
... in order to get an estimate of the uncompressed size of a compressed,
extended-format DSORG=PS dataset.
The documentation in "Managing Catalogs" is a little thin.
- is UDATASIZ the uncompressed size?
- which flags should I use to determine that the value in UDATASIZ is valid
- VVRNFLGS? not bit x'80'?
- COMPIND bit x'40'?
Pointers to additional documentation or usage information would be
appreciated.
I'm thinking what's required here is some creative correlation between "Managing
Catalogs" and the "Interpreting LISTCAT Output Listings" appendix in the "Access
Method Services for Catalogs" book. How about "COMP-USER-DATA-SIZE" and
"USER-DATA-SIZE"? I'll leave the flags for you.
