Subject: RE: Determine Subfile Page
SFLRCDNBR (Subfile Record Number) keyword for display files You use this field-level keyword on the subfile-control record format to specify that the page of the subfile to be displayed is the page that contains the record whose relative record number is in this field.

Subject: Determine Subfile Page
True or False? If a subfile has no input fields, it is impossible for the RPG program to determine which 'page' the subfile is on.
Example: I have an invoice lookup program with a subfile that has no input fields - it just shows one line of information per invoice. The subfile control record has a single input field where the user can type in and invoice number and go to a screen that shows the invoice detail information. When the user presses F12 to return from that screen, they want to go back to the subfile 'page' that they came from (and not back to the beginning of the subfile, which is what the program is currently doing).
If I can determine the subfile's current 'page' then I can force the subfile back to the 'page' the user came from.
How can this be done if the subfile has no input fields? SFLCSRRRN doesn't help because the cursor is never within the subfile.
Thanks in advance for any thoughts on this.
