Sorry i didn't get you. My question is, merely by seeing the program i have to say whether it is using vsam file or not.

You cant unless your shop naming conventions are different for VSAM, Flat file and GDG (as we do in our shop).

This should be in interview or one of the other rookie forums.

you might be able to tell from the code, whether a program is intended to perform i/o on a vsam file ksds - key, rnn - got a key. esds, no key, no nothing, pretty hard to tell from code. besides, the code could be in error.

no professional would make a decision purely based on the code. If the file allocations for a program contain a DSN, a professional would look at the file attributes and not the code in a program.
