Actually, I know which fields are from database files by their names. So far every application I've worked on, or written, for the AS/400 so far have had naming schemes to distinguish field variables from program variables. In one application the first 2 characters out of 6 stated what file it was from. In another program the last 2 characters stated what file it was from. In databases I've designed, I've used the first 2 chars. True, CMZIPC may mean next to nothing, but it tells me that, first it's from the Customer Master file and 2nd, it's a ZipCode. Not to be confused with VMZIPC which is the Vendor Master zip code. ZIPC or ZIPCODE would be a program variable.

Perhaps you intuit it from the source? Now THAT would truly be an awesome skill. Joe
