The user selects a radio button by moving the cursor until the radiobutton associated with the desired field is highlighted. The radio button ON character is displayed automatically in the highlighted field, and the OFF character is displayed in all other radio button fields in that group. When the user leaves the radio button group, the field that is ON is the field that is selected. By default, keys that move the user out of the group include: KEY_TAB, KEY_STAB, KEY_F7, KEY_F8, and KEY_ENTER. Note that selection from a radio button group always results in a single selected value.
When the user is in a radio button group, input processing is controlled by the radio button event table, Event table:RADIOETP. You can change the key assignments by modifying the event table. See Chapters 37 and 39, "How Event Processing Works" and "Installing Event Functions and Modifying Event Tables," for more information.
