Ensuring numeric input

[simplsol at aol.com]

Richard,
To make the world safe for Intel we could do the dirty work in a 
variable:

on closeField
put me into temp
add 0 to temp--of course any number would do (0.00001 or 10 or ?)
if the result is not empy
then answer "This is not a valid number:"
end closeField

 But is zero counted as zero, or would it add 0.00001 in Intel chips?
