Re: Clear entire field vs substring

Man, this is a lot of work when the system will help you so much! As has been said in this thread - oooh! that rhymes! - an EVAL basically does a set and pad, probably - Chuck's reply suggests this. I mean, Albert is not extracting values from the middle of the workfield, is he?

An = is an implied EVAL - NOT a MOVE.

Hey, I love to get complicated, too - but I'm learning!!

If workfield is varying-length, the system knows

Albert,

Can you use the length of Newdata to set the values you extract from workfield? That way you don't have to clear it at all.

For example...

len = %len(%trimr(Newdata));

fullfield = %subst(workfield:1:len)

x = len - 3;
partialfld = %subst(workfield:4:x)

Subject: Clear entire field vs substring

I have a work field that is 2000 bytes (to allow for the longest possible string value). The length of the data being moved to it varies and can be quite short. I have to clear the work field before I move the data.

Which is better:

workfield = *blanks


len = %len(%trimr(Newdata));
%substr(workfield:1:len) = *blanks;

Thanks,

Albert
