WRITE ... AS CHECKBOX

WRITE - Output as checkbox

Effect

Outputs the field f as a checkbox. The contents of the first character of f is interpreted as the "status":

' ' = not selected
'X' = selected

The user can change this as required.

Note

To prevent the user changing the contents of the checkbox, you can use the addition ... INPUT OFF. The checkbox is then nothing more than a status display and can only be changed by programming.
In technical terms, a checkbox behaves exactly like an input field with a length of 1 ( FORMAT INPUT).

Examples

DATA: MARKFIELD(1) TYPE C VALUE 'X'. 
... 
WRITE MARKFIELD AS CHECKBOX.		 "checkbox selected 
MARKFIELD = SPACE. 
WRITE MARKFIELD AS CHECKBOX.		 "deselected 
WRITE MARKFIELD AS CHECKBOX INPUT OFF. "deselected, protected
