RE: Using RRN 0 to do Setll on arrival sequence file






Actually my theory is still correct.
As Charles previously mentioned
"Setll w/rrn = 0 means, position the file one record before the 1st
record, ie. before the beginning of the file."
Whereas SETGT w/rrn of 0 means, position the file one record after the
record before the 1st record, i.e. at the first record.
Now everybody do what I have just done. That is re-read what I have just
written and say
"What the @!#$%^&*()_ is THAT suppose to mean?"

I would have to disagree with that theory.  Simply because it goes
against what setll suppose to do.  If a file has a 3 chars long key
field and the file contains records below:
AAA
BBB
CCC

If I do setll with *blank, I would expect it to go to BOF even though
blank record does not exist in the file.

Interesting to know that setgt 0 actually work.  That kind of blow away
Alan's theory that RRN 0 is not a relative record number and it doesn't
know who to position the cursor.

I said:

In a file where the first RRN is 2, SetLL 1 positions to the deleted

RRN

1 record, not to EOF.  (I'm guessing it positions to the deleted

record, though I know it doesn't position to EoF.)

What I was getting at is you can SetLL to any relative record number
from 1 to highest RRN in file and not position to EoF, regardless of
whether or not any of those records have previously been deleted.  That
concept is a guess, but seems to be how it works.  Once you exit that
range of RRNs, you will not find a record and position to End of File.
