Re: Externally-defined, arrival-sequence file - getting to the last record

Yep, removing the parenthesis did the trick!
 
I guess I was thinking about key lists and how they are always in 
parenthesis... I guess I can see a consistency if there is only a single 
element in the key.
 
Using *HIVAL was my choice, but I had it in parens also...  Also learned that I 
can use *END to get to the last record.
 
Thanks alot, guys.

Have you tried removing the parenthesis?

In other words, do:

CHAIN rrn Filename;

instead of

CHAIN (rrn) Filename;

That would be my first guess, anyway.
