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

Interesting thing to me is why the compiler even allows it. It should throw
it out as an error because you are comparing an alpha field to a zero (A
numeric field).

Not so. The compiler will - and should - allow it.

*Zeros is _not_ a numeric - it is a figurative constant. By definition that takes on the data type of the field against which it is used - in this case a character field. So in this case *Zeros is a string of character zeros.

Had the comparison been against a numeric zero e.g If charField > 0; then the compiler would have correctly diagnosed it as an error.
