Jim,

My intention was opposite. I want that users type 5 digits only - no dots, commans, minus/plus, etc. Right now I changed my code this way:
if len(lcString)<>5 or !IsNumeric(lcString)
=messagebox(...)
return .f.
endif

where lcString is user's input (in editbox) and IsNumeric is George's function.
