varGet() --> GetVarValue

        Returns the current value of the GET variable.  For simple GET
        variables this is equivalent to executing Get:block:

        aGet:varGet() == EVAL(aGet:block)

        However, if the GET variable is an array element, EVAL(aGet:block)
        will not return the value of the GET variable; in this case, you must
        use varGet().  An example of varGet() may be found in the READMODAL()
        function, defined in Getsys.prg.
