Defining Radio Buttons
To define the input field of a parameter as a radio button, you use the following syntax:
PARAMETERS <p> ...... RADIOBUTTON GROUP <radi>......
Parameter <p> is created with type C and length 1, and is assigned to group <radi>. The maximum length of string <radi> is 4. You can use additions TYPE and LIKE, but you must refer to a field of type C with length 1. You must assign at least two parameters to each <radi> group. Only one parameter per group can have a default value assigned using the DEFAULT addition. The default value must be 'X'. If you do not use the DEFAULT addition, the first parameter of each group ist set to 'X'.
When the user clicks a radio button on the selection screen, the respective parameter is assigned the value 'X', while all other parameters of the same group are assigned the value ' '.
