1) This will only work on EDITABLE Text Widgets, this will always return an
   error if the Text Widget is read only.

2) The last function call should be.


    if (XtTextReplace(w, 0, last, &text) != XawEditDone) {
	/* an error occurred */
    }

There is no guarantee that XawEditDone is zero, it just happens to
be that way in the current implementation.  For further information
on this function consult the Athena Widget Documentation (pp 26).
