RE: Clear entire field vs substring

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
