RE: What's the error?

Yes, Scott, that reaffirms what I was mumbling about in my response.  My last 
experience with
variable-length fields was that you had to manually update the 2-byte length at 
the beginning of
such a field when writing or updating it in RPG, and now RPG-IV handles that 
automatically. 
(Although I may be confusing variable-length database fields and VARYING 
program-defined fields.)

Why be "silly" and "search something you just added"?  Cuz I didn't write the 
%scan and %replace
code and am still trying to get trying to get my brain wrapped around the new 
things added since
v3r2.  Which I was stuck at up until three months ago - so while all you guys & 
gals were posting
your real life experiences with v4 & v5 stuff, I was relegated to reading and 
wishing.  You were
"there" before awhile ago, weren't you Scott?  Anyways, add VARYING to the mix, 
and my feeble mind
just starts to overload.  I've got a lot of catching up to do.  We're at v4r5 
now, and are
upgrading to v5r2 this weekend!  I can't remember the last time I've worked in 
a shop that was at
the most current release.
