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

Ok, 

"If the SETLL operation is not successful (no records found condition),
the file is positioned to the end of the file."

SetLL 0 finds no record, as there is no such thing, so the file is
positioned to EoF.

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.)


SetGT 0 will accomplish, Lim, what you're looking to do with SetLL 0.

Lim - the simple answer is that 0 (zero) is NOT a relative record
number, so how can it position.

Read will fail after setll with rrn 0, which take us back to the 
original question of why would setll with rrn 0 set the cursor to end 
of file.  It should set to the beginning of file according to setll 
documentation.

Ah, but did you try doing a read after the setll with 0?

It'd be interesting if the read works.

Uummm.
For a non empty file, READ will be successful when cursor is at BOF.
READ will failed when cursor is at EOF.  The opposite applies for 
READP.
So, for me, technically, they are not the same.

<clip> technically the begiining of the file is and "end of file" 
You can set on EOF from READP also.
