Output to the BODY Area of the Main Window
If you omit the parameter WINDOW in the function calls for WRITE_FORM and WRITE_FORM_LINES, the system directs all output to the main window of the form. It immediately formats the the passed text or the desired text element and places them into the output queue. Once formatted output lines are in the output queue, you cannot delete them anymore.
The system ignores any entries for the parameter FUNCTION, that is, evaluates them as APPEND.
