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

[Kurt Anderson <kurt.anderson@xxxxxxxxxxxxxx>]

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;
