# to synthesize variable names for each instance of the dialog.  The dialog
# gets a TK pathname $id, from which it strips the leading "." to make a
# variable suffix $vid.  Then you can get the actual value out by asking for
# [eval concat $$variablename].  There should be an easier way but I don't see
# it yet.
