[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

The sad thing is that there's plenty of code around that is, in spirit, just
like this example.  I've had to modify it.  Some of it was written by former
employees who were highly regarded.  I'm sure I'm not the only one who's
seen stuff like this.  

Glad you qualified your answer with the assumption that the result field was
defined as two positions. <g>
