We are a batch system that is converting from NetExpress 5.1 to Visual Cobol 2022. When compiling we are getting errors with the file name and assign name being the same. This compiles without an errors in NetExpress.

FD G05
BLOCK CONTAINS 0 RECORDS
LABEL RECORDS ARE STANDARD.

The error is COBCH0005, User-name G05 not unique
the error is on the SELECT G05 Assign to G05 line. Do we have to make the file name and assign names different or is there another way?

Hello,
Are your files mapped or ASSIGNED externally via an environment variable (external) or are you looking to move a filename into a working storage data item (dynamic)?

If externally, you need to set the compiler directive: assign"external". The default is assign"dynamic". In the dynamic case it is expecting a data item called G05 where you would move the actual physical file name into...e.g.:

move "myfile.dat" to G05.

As of now there is a conflict with the FD and the fact it is expecting a working storage data item called G05. 

If your intention is to map the G05 to file name that is externally assigned via environment variable, then set the directive assign"external"
