May crash if there is a table open with a field named "tcEmpno". I mean if you're going to list the assumptions, might as well add the lack of mdot involves a big assumption.

If I write code for other programmers to use, I can't be sure they will pass the parameters properly. If I

?SQRT("X")

VFP does give an error. What should my code do if you improperly pass parameters?
