Answer / vikas pujar
Its not possible to identify if Input file is VSAM or not just by looking at JCL. Usually companies have naming conventions for for DDnames. If VSAM, use V1234, If Sequential use I3456 , If output file O5678. So if use these we can identify.

Answer / raghav
Its not possible to identify just by seeing job,
one way to know is try to do hyper Browse on that file, If
it opens then its not a VSAM.
How to do Hyper browse:
Tpye HB on command line and keep the cursor on that file
and press enter, if its a seq file it will be opened in
browse mode.
