RE: NumberField = AlphaField in rpg/free

There are a couple of things to watch for with atoi().  It's limited to the
size of an integer and returns zero when it sees zero or an error.  You
should use it only when you're already sure you have valid numeric
characters and won't cause overflow.  atol() handles larger numbers--long
integers, but has the same error handling.
