	You can turn your checkboxes into radio buttons very easily. Simply add a group number (1,2,3,etc) in the attribute field and your checkbox will be converted to a radio button as ScreenIO builds the screen.		You can turn your checkboxes into radio buttons very easily. Simply add a group number (1,2,3,etc) in the attribute field and your checkbox will be converted to a radio button as ScreenIO builds the screen.

	You oftentimes will want to tie a group of Radio Buttons to a single field in the data file. In that event, specify the same field name for every radio button, and specify the True Value that you want associated with each Radio button in the group. For falsehood values for all the controls in the group, specify a value of "~ignore~". This will instruct ScreenIO to ignore the falsevalue, saving the truevalue from the currently selected radio button.		You oftentimes will want to tie a group of Radio Buttons to a single field in the data file. In that event, specify the same field name for every radio button, and specify the True Value that you want associated with each Radio button in the group. For falsehood values for all the controls in the group, specify a value of "~ignore~" (but no quotes). This will instruct ScreenIO to ignore the falsevalue, saving the truevalue from the currently selected radio button.

	The Validation attribute identifies the Custom Screen function that gets triggered whenever the data in the control is changed. You can use this event to ensure that only valid data gets saved in the database. If your validation event returns false (0) or a null string then the data the user entered is thrown out, and the previous value is replaced in the control.

If it is blank, it does not read the screen, and instead performs the screen's initialize event, the custom code (if there is any) for initializing a new record into the data file.
