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

I was thinking that too, Alan, but check it out:
"Character/numeric fields: All zeros. The value is '0' or X'F0'. For numeric float fields: The value is '0 E0'."
This is from:
http://publib.boulder.ibm.com/infocenter/iadthelp/v7r0/index.jsp?topic=/com.ibm.etools.iseries.langref.doc/c092508633.htm

However, I think the comparison is not the way to do things. Convert the left value into a numeric, then compare it to zero.

I don't understand why it would ever work. You are comparing an alpha field
to numeric field. Seems to me it should always fail. Did you mean

If %Dec(%Trim(Field):8:4) > 0;

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?
