# Create A Radio Button

\[ _Type_ code = **||r** \] These are similar to checkboxes, but considerably trickier to use because they are must be grouped somehow since only one within a group can be set at one time. If there is only one set of radio buttons on the screen, then these form a single group. Otherwise you must use [AUI\_CONTROL](aui_control.md) to create a group box to contain the radio buttons. Note that because of these complexities, it is usually much easier to use a combo box to present a choice of mutually-exclusive options. (Combo boxes are easy to implement – just specify **|G** and use the _setdef_ parameter to list the choices.) See [Radio button Control](radiobuttoncontrol.md).
