Kevin;
I would not rely upon the naked reference to
get you the proper node (especially when you are testing for the non-existence
of the target node. Use the whole reference in the set. Basically,
the result of the naked, $ZREFENCE is likely to be set near where the $D()
reference failed, not the apparent full reference. You might try capturing
the $ZREFERENCE after the naked gets set. It could be
interesting.
Best wishes;
Chris

lookup question: Aliases in PATIENTfile

file.
This is it's set node:
S:'$D(^DPT("B",$E(X,1,30),DA(1),DA)) ^(DA)=1
So, to me, this looks like it is affecting the "B" index of the
entire
file, and inserting the alias name into the "B" index.
So I look in ^DPT("B",AliasName), and I don't find my entry. This may
explain why it's not working.
That's certainly an unusual approach. The whole point of mnemonic
cross-references is to allow you to create many-to-one indices (using
alternate names) like this. In my opinion, multi-index lookup is much cleaner,
but the PATIENT file has been around for a long time.
