Disable Connections
If a row of the connection argument begins with "radio", the row specifies a radio connection. A row corresponding to a radio connection has the form:
     radio, F1, F2, ...
where F1, F2, ..., denote the names corresponding to fields in the dialog. One and only one of the check boxes in the connection is true. If one of the false boxes is selected, it is set to true and the others are set to false. If the true box is selected, no change occurs.

Program
     clear
     cap = "Radio_callback"

          "checkbox, Gear, 2, false", ...
          "checkbox, Adams, 2, false" ...

     connection = "radio, Runge, Gear, Adams"
     easydlg( cap, but, msg, lay, connection)
     function Radio_callback(button) begin
          print "button =", button
          print "Runge  =", easydlg("Runge")
