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

No, the %eof will only be *on for
3   setll      MYFILE

the subsequent read will in fact read rrn 4, which is there, and therefore
%eof will NOT be *on.
Sometimes you may want to know if a particular record exists, your NOT
bothered about the data on the record.
For example
does account # 123456789 exist
123456789   setll Checkfile
            If    %eof(Checkfile)
            account number does NOT exist
            else
            account number 123456789 exists
            endif

There is no need to do a subsequent read. This will prove whether or not
that account number exists.

Do you mean eof will be *on if I do below and RRN 3 does not exist in
MYFILE?

3   setll      MYFILE
      read     MYFILE
      eval     eof = %eof

Yep - this is normal behavior.
For example, lets say you have a file with the following RRN's
1
2
3
4
5

using RRN of 3 to do SETLL on the sequential file, you will NOT get %eof
= *on.
Delete record 3, then doing the same SETLL of RRN 3 WILL result in the
%eof = *on

When I use 0 as RRN number to do SETLL on an sequential file and do a
read, I got %eof=*on.  (I know using *start or RRN of 1 will correct
my problem).  Just curious as if this is a normal behavior.
