Re: %EOF with READC -- RPG400-L

Bob,

Consider me kicked. The manual, in fact, omits the file name in thecode example. I prefer, though, including the file name here and%found(), etc., simply for clarity and, in this case, consistency (theREADC is, after all, the preceding op; not like it's buried somewhereelse in the code). Just one of my (many) idiosyncrasies.

Yes, Jerry, kick yourself. <vbg>
You don't specify the record format name on %EOF, you specify the file name
only. That's one of those RPGIV-sucky design features.I would simply leave off the qualifier on %EOF.

Subject: %EOF with READC
I know I'm going to kick myself as soon as I hit the Send icon becauseI'll see the error just a microsecond later.
But I cannot get the %eof() built-in function to work with subfiles. Themanual says it will (pages 479 and 710), but it doesn't like me. I havepasted what I think are the relevant pieces of code. Hopefully someoneout there has better eyesight than I.
   FIT002FM CF E WORKSTN INFDS(WSDS)
   F SFILE(IT002B:RRN1)

   EXSR #Load; // Load the subfile

   EXFMT IT002BCTL; // Subfile control.

   READC IT002B; // Find the selection, if any.
   IF not %eof(IT002B);
   aaaaaa
   a 011400 Parameter IT002B is not valid for built-in function %EOF.
   %EOF is ignored.

From the WDS ILE RPG Reference manual (pg 710):
You can specify an indicator in positions 75-76 that will be set on whenthere are no more changed records in the subfile. This information canalso be obtained from the %EOF built-in function, which returns '1' ifthere are no more changed records in the subfile and '0' otherwise.
Thanks.
