Yes, that's right, unless you rename the fields inside the pgm, or give them a prefix.

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!

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?
