RADIO-SET phrase
Describes a radio set representation for a field or variable. The RADIO-SET phrase is an option of the VIEW-AS phrase.
Note:
Syntax 
 
RADIO-SET
  [ HORIZONTAL [ EXPAND ] | VERTICAL ] 
  [ size-phrase ]
  RADIO-BUTTONS label, value [ , label , value ] ...
  [ TOOLTIP tooltip ]
HORIZONTAL
Specifies that the radio buttons are aligned horizontally. Vertical alignment is the default.
VERTICAL
Specifies that the radio buttons are aligned vertically. Because this is the default alignment, you do not have to supply this attribute.
EXPAND
Pads all button labels to be the width of the widest radio button label. This ensures that the buttons are evenly spaced. Use this option only in conjunction with the HORIZONTAL option. If you do not specify this option, the individual radio buttons are spaced evenly if the lengths of the labels vary.
size-phrase
Specifies the outside dimensions of the radio-set widget. This is the syntax for size-phrase:
 
Syntax 
{ SIZE | SIZE-CHARS | SIZE-PIXELS } width BY height 
For further information, see the SIZE phrase reference entry.
RADIO-BUTTONS label, value [ , label, value ] . . .
A list of radio buttons whose selections are mutually exclusive. Each button is composed of a label and value pair. The label is a character string that is the label for the radio button. The value is the value to be assigned to the field or variable if the radio button is selected; value must be a valid value for the field or variable.
You can designate a character within each label as a navigation mnemonic in Windows. Indicate the character by preceding it with an ampersand (&). When the radio set is displayed, the mnemonic is underlined. The user can choose to the specific button by pressing ALT and the underlined letter.
Note:
TOOLTIP tooltip
Allows you to define a help text message for a text field or text variable. The AVM automatically displays this text when the user pauses the mouse button over a text field or text variable for which a tooltip is defined.
You can add or change the TOOLTIP option at any time. If TOOLTIP is set to "" or the Unknown value (?), then the tooltip is removed. No tooltip is the default. The TOOLTIP option is supported in Windows only.
Example 
This procedure displays a radio set that consists of three radio buttons and prompts the user to select one of the buttons. When the user selects the button, the program displays the text “This event occurred on” and the date value of selected button.
