Re: Weird problem with *ZERO on compare of character value

I'm surprised that you can even use *ZEROS since it is normally for numeric comparisons. It may have something to do with what it thinks the sign is when it does the comparison. In an alpha comparison the sign doesn't come into play so you are really only checking to see if it is zero or not. Assuming you can't use a numeric comparison then you can try:

If %TrimL(Field) <> '.0000'

I have a character field defined as 9A.
This field is an edited representation of a 8.4 numeric field with
leading blanks.
Given the value '     .1525', when I compare it to *ZERO using the
instruction If %TrimL(Field) > *ZERO, the compare fails.
Using a value of '0000.1525', the compare also fails.
Using a value of  '    1.0000' or anything with a value to the left
of the decimal point, the compare works.
I am on a V5R4M5 system with PTF TL58305 installed.

Can someone explain why this does not work as I would expect?

Thanks,
