IF TYPE ("MyVar") <> "U"
     WAIT WINDOW TRANSFORM (MyVar)
ENDIF

TYPE won't break whatever you feed it. Remember to include the quotes around the variable name as TYPE essentially does an EVALUATE first.

If you're using VFP 6.0+, the TRANSFORM function, with only one parameter, will convert the variable to a string which is compatible with the WAIT WINDOW format.

Enjoy!
