Re: Compiling a program with two files having the same name

[Stuart Rowe <rowestu@xxxxxxxxx>]

Here's a good one: declare one (or both) of the files as program
described (pick any name you want as it won't matter at compile time), then
describe it with a data structure and perform IO ( read, write, etc) with
structures.  A throwback to the S/36 and beyond, but it still works just
fine!

something like (forgive my lack of columned-ness, I'm at home)

Finput    IF   E                        disk
Foutput   O  A F   512                  disk

D oRecord      E  DS                 qualified extname( realfilename )

 /free

  read input;
  dow not %eof( input );

    oRecord.OFIELD1 = NFIELD1;
    etc...

    write output oRecord;

  enddo;

 /end-free

You can use OVRDBF at runtime before opening the files.
