In RPG:

If you have two input files with same-named fields, the fields must have the same attributes (both numeric and the same length, or both alpha and the same length. If not, the compile will fail.

When you read a record from file1 with field CUSTID="CUST1", then read a different record from file2 with field CUSTID="CUST2", then the value "CUST1" is gone, and only the most recent value is available, which is CUSTID="CUST2".

So technically yes you can have two input files containing the same field names, but it is useless, only compiles sometimes, and will give meaningless results!

Subject: RPG IV versus COBOL - field naming

Hello.

I COBOL, we can have two inputfiles containing the same fieldnames, and we can qualify the names when we use them(MOVE FIELDA in FILEA to FIELDB IN FILEB etc.).

In earlier RPG, this was not possible. We had to have a unique name on every field.

My question is: Has this canged in RPG IV? Or do we still have to give each field a unique name?

Does anyone know?

Mvh.
