Using REXX can I find the VSAM file attributes space allocation and space used?

Are LISTCAT and/or LISTDSI not giving you what you need?

you can get all information from LISTCAT
and then you have to calculate the allocated
tracks, used tracks and percent. here is an
example from my vsam dataset rexx.

ATRK = ARBA/CISZ/CICA*TRKS
UTRK = URBA/CISZ/CICA*TRKS
UPER = UTRK/ATRK*100

ATRK = FORMAT(ATRK,,0)
UTRK = FORMAT(UTRK,,0)
UPER = FORMAT(UPER,,0)

Allocation
Allocated Tracks: 19125
Allocated Extents: 3

Utilization
Used Tracks: 18810
Used Percent: 98
