SET dialog index RADIOBUTTON row col text [var1|* w h * fg bg font] [ /A|L|R ]
The radio buttons are the only controls where one variable is bound to multiple controls. A new radio button group is started when a variable name var1 is specified. For all other radio buttons of the group the argument var1 must be set to '*'. The value of var1 is set to activeindex-groupstartindex, where groupstartindex is the index of the first radio button of a group and activeindex is the index of the activated radio button of the same group. Only one button in the group can be activated at one time.
| var1 | The name of button index variable (only for the first button in the group). |
See Common arguments for a description of the parameters not described here.
Using radio buttons may lead to problems because the function searching for the first button in a group does not always work correctly. It only works if no other control (e.g. a groupbox or a static) is placed between the buttons of the group.
