12.10 Radio Button Widget – RADIO
The RADIO widget allows you to display buttons for making a selection. Radio buttons differ from
checkboxes in that only one button can be filled in at a time, while checkboxes can have many filled in.
Therefore, radio buttons are interconnected. If one button is checked then the others will go to or
remain as an ‘unchecked’ state. The RADIO.EZM file in the \EZSYS\MACROS directory contains an
example of this widget. It can be invoked by typing PLAY RADIO from your terminal program.

Pressing high, medium or low will send either a RB0, RB1 or RB2, respectively, to the Command
Port.
The RADIO command contains eight different values.
The [ID] value 1-99 is the id number of this particular widget. Although radio buttons are connected as
a group, each button still needs its own id number.
The [x] and [y] values designate the location of the widget on the screen as the XY coordinate of the
upper left corner.
