Re: [V4R5] File in arrival sequence: Correct way to place pointer at BOF

Patrick, even with implicit OPEN, since RPG does that, you always are at
the beginning of the file, and no matter if it has a key or not, it will be
at BOF.
So, issuing a READ will get the first record. RRN works even with a CHAIN,
and only if it's not keyed:

CHAIN 1 MYFILE;

should work too.

Hello,

I have a PF that is used as temporary storage for a cpyfrmimpf. It has no
keys whatsoever and is truncated before each run (rmvm, addpfm). I
reference that file in RPGLE without the K flag, because it has no keys.

What is the correct way to place the file pointer at BOF?

Neither setll *START, nor *LOVAL work: The compiler complains that these
are invalid. Setting it to 1 makes the program compile. But this is now
based on the assumption that there is always a RRN 1 in the file.

Did some Googling but did not find enlightenment. Hints are welcome!

:wq! PoC
