George,

IsDigit() checks only first symbol, so it's not suitable for my situation. Type() works fine.

Example:

myNumber='12345'
type(myNumber)='N'
isDigit(myNumber)=.t.

myNumber='1hffhhf'
type(myNumber)='U'
isdigit(myNumber)=.t.


>>>
>>>You can use the funcion TYPE.
>>>Example:
>>>
>>>IF TYPE(mynumber) = "N"
>>> WAIT WINDOW "IT'S A NUMBER!!!"
>>>ELSE
>>> WAIT WINDOW "IT'S SOMETHING ELSE!"
>>>ENDIF
>>>
