Re: Moving a field and removing blanks

But EVALR trumps them all - as other posts have suggested. No intermediate field - no substring - no length function.

It came out in V4R4, so far as I can tell, so everyone should be able to use it.

Nothing much cleaner than

evalr text = %trim(text);

Without intermediate field:

%Subst(Field50:
(51 - %Len(%Trimr(Field30))):
%Len(%Trimr(Field30)))
= %Trimr(Field30);


With an intermediate field, Alan's is probably the best. And even
overall, I like Alan's because it only trims the field once. That's
worth the tradeoff of an intermediate field. Note that either method
will require you to check for a blank string; if Field30 is all blanks
either of these will give you an RNX0100 string position error.
