One more SAPScript doubt

Hi,

I have got one more doubt in SAPScript.

I am defining a logo window and main window in SAPScript.

Now say I am not passing any data to this SAPScript form.

When I do the printing after going in some transaction I just want the form to print with the logo window in which I am calling logo graphics using, "INCLUDE ZNORDAM OBJECT TEXT ID ST LANGUAGE EN".

So my question is even if I am not passing any data to layout do I still need to use open_form, write_form and close_form function module in print program even if I just want to print out the layout ?
