I've created two physical files, INVOICES and LINEITEMS, and am
attempting to build an interactive order entry application which will
use them. I've successfully designed the subfile and subfile control
DSPF files and I'm now attempting to write the RPG. I'm using ILE RPG
on V4R5 if it makes any difference. I've determined that I need to
specify in the F-spec that the file uses subfiles and which field is the
relative row number. The way my files are set up each invoice has an
INVOICEID and each line item has a field where it specifies which
invoice it belongs to by filling in the INVOICEID. This should occur
behind the scenes without the user needing to enter it. What exactly is
the relative row number? How do I specify that the rows
displayed/processed should be limited to rows matching the current
INVOICEID? Is there a good tutorial explaining this somewhere? The IBM
RPG documentation/redbooks have been less than helpful.
Thanks,
Kyle Goodwin
