You can browse the VSAM using fileaid just by providing the cluster name (i.e., without .DATA or .INDEX).

The data portion, as you may guess by its name, is the part of the cluster that contains the data. The index is created from the data portion, and is used to access the data on a random or keyed basis.

The easiest way to see what's in the file is to REPRO it out and than play with the flat file.

That way, if you screw up the flat file, you won't have screwed up production too.
