I dont know, what you are talking about. If that is a GDG stuff, its not a VSAM.

Anyway... VSAM file would be associated with a DATA and INDEX component, if you are on 3.4 Screen... But the question is where you are actually looking at the file...

VSAM might have the DATA & INDEX suffixes, but this is not a must.

GDG generation will have the GnnnVnnn suffix (but not the base GDG).

The best way, when in 3.4, is to shift right-left using PF10/PF11 (usually) and take a look at the DSORG column.
