IFGT vs. IF

["Jon Paris" <Jon.Paris@xxxxxxxxxxxxxx>]

The problem with relying on the evaluation sequence of the IF is that
someone else may change it later - it is a likely change to be made by an
efficiency fiend since the firsttime test will only ever give true once so
why not have it last?

A better answer I think is to simply change the definition of the line
number to be type I or U.  It won't cause any problems, will be more
efficient, and won't cause this error.

The reason the old IFxx test works I suspect is that like fixed form math
operations, it simply truncates the excess digits and ignores them.
