Hello,

Assuming that you are using CW_BGroup ... and that things haven't changed much
since version 5.2 ...

To control the radio buttons (exclusive) set the Set_Value keyword to
Widget_Control to the button index (starting from zero). As an example, to
have the second button of 4 buttons set on use Set_Value = 1

To control the check boxes (non-exclusive) set the Set_Value keyword to
Widget_Control to an array of on/off flags. As an example, to turn on the
second of the 2 button group but leave the first one off use Set_Value = [0,1]

You can also set the values when you first define the button groups with the
same keyword in CW_Group.

Hope this helps.

Ben
