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

Since 0 is not negative the system won't give an error. technically the 
begiining of the file is and "end of file" You can set on EOF from READP 
also. 
I also found this part in the manual
.
The following operations, if successful, set %EOF(filename) off. If the 
operation is not successful, %EOF(filename) is not changed. %EOF with no 
parameter is not changed by these operations.
CHAIN (Random Retrieval from a File) 
OPEN (Open File for Processing) 
SETGT (Set Greater Than) 
SETLL (Set Lower Limit)
When a full-procedural file is specified, this function returns '1' if the 
previous operation in the list above, for the specified file, resulted in 
an end of file or beginning of file condition. For primary and secondary 
files, %EOF is available only if the file name is specified. It is set to 
'1' if the most recent input operation during *GETIN processing resulted 
in an end of file or beginning of file condition. Otherwise, it returns 
'0'.

That is curious then.  Why doesn't SetLL 0 produce the same result?  And
since it doesn't, then why is it positioning to the end of file?
Interesting indeed.

You get CPF5025 - Input operation past start or end of file :-)

What happens with SETLL -1?

Just wondering.

Your welcome Lim, but like I said in a previous e-mail. An RRN of 0

will

NEVER exist. We just assume that the next number to 0 will be 1. But

if

you
are trying to access something that will NEVER exist, how is IBM to
process
it?
