All of these solutions will, as far as I can see. If they don't the result
won't be as sought. Do you really care that the field is momentarily blank,
since there's no chance to intercept it in that condition? Or maybe I don't
understand your objection.

However the OP wanted to retain data that is in the result field. Eval
or EvalR will clear the field before assigning the value.

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.
