Re: Reduce code of CHAIN

I have a question. For the last few years we have been coding chain
statements like this:

abc chain file1
    if %found(file1) and not %eof(file1)

Do we not have to use the %eof on chains? I know you have to use them on
reads? Any help would be appreciated. thank you

Jeff, you only need to test %found.

Checking %eof is either wrong or redundant.  

It's wrong prior to V5R1; chain didn't affect %eof at all.  If the file
had previously reached eof, the test would fail even if the chain found
a record.  

It's redundant starting in V5R1; chain sets off %eof(filename) if the
chain is successful, but it doesn't have any effect if the chain doesn't
find a record.  If %found(file1) is true, then "not %eof(file1)" would
also be true.  If %found(file1) is false, then it doesn't matter about
%eof(file1).
