Thanks, everyone for your help. As some of you pointed out, I need to do this without there being a value in the field.
Sergey, your code:
? -AT(SET("Point"), PADL(MyField1,20)) % 20
does exactly what I need. That is a brilliant solution!
The link entitled "How to check if variable is Integer" says "FoxPro doesn't provide a direct way to check if variable is integer." TYPE() has always worked fine for me, even for variables.
h = 0
? TYPE('h') && Yields 'N'
