askERT TEXT! = NULL
Println (Text)
(4) gstring
l Use $ {expression} syntax, you can include any expression in the string, similar to JSP EL, Velocity
l Any valid Groovy expression can be included in the method call using $ {...}
l When using a string containing $ {expression}, the CString object is created to include the text and value used in a string.
l CString uses an inert evaluation method, only if you call the toString () method
