RE: Moving a field and removing blanks

If you have a field the following field:
FIELDA = "1234 "

And you want to put 89 at the end to give a value of "1234 89", then saying EVALR FIELDA = '89' is not going to do it.

All of the substring solutions appear fine. I was just taking issue with Vern's statement to ignore using the substring functions and simply do plain EvalR (as per his example).

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.
