What is the difference between OPEN_FORM and CLOSE_FORM?

Submitted by: Administrator
OPEN_FORM - This module opens layout set printing. This function must be called up before we can work with other layout set function like WRITE_FORM.

WRITE_FORM - Output text element in form window. The specified element of the layout set window entered is output. The element must be defined in the layout set.

CLOSE_FORM - End layout set printing. Form printing started with OPEN_FORM is completed. Possible closing operations on the form last opened are carried out. Form printing must be completed by this function module. If this is not carried out, nothing is printed or displayed on the screen.
