AM:

I would use something more like this.

dcl-ds WhsLookup_t template;
Whs char(2);
*n char(1);
Duns char(9);
end-ds;

dcl-ds *n;
*n char(12) inz('10 006477244');
*n char(12) inz('18 612726414');
*n char(12) inz('20 612726414');
WhsTbl likeds(WhsLookup_t) dim(3) pos(1);
end-ds;

And in case it wasn't obvious, you would lookup by WhsTbl(x).Whs
and when you get a hit, you use WhsTbl(x).Duns to get the DUNS
number for the matching warehouse.

Oops, I forgot to include the "qualified" keyword. Here is a live
running example -- but without the additional blank space that makes it
more readable..

dcl-ds Match_Entry qualified template;
Ind char(1);
Code char(6);
end-ds;

dcl-ds Match qualified;
*n char(7) inz('E200000');
*n char(7) inz('P100000');
*n char(7) inz('R400000');
Entry likeds(Match_Entry) dim(3) pos(1);
end-ds;

idx = %lookup(iGroup: Match.Entry(*).Ind);
if idx = *zero; // if industry not found
iSequence = iGroup; // categorize by industry group
else; // else use assigned IPIC code
iSequence = Match.Entry(idx).Code;
endif;
