Margins

Margins of the printed output are expressed in terms of lines and characters

Left Margin—number of character positions for the left margin. The default is 0.
Right Margin—position of the right margin as measured in character positions from the left edge of the page, not from the left margin.
Top Margin—line where printing should start on each page. The default is 0.
Bottom Margin—number of lines from the bottom of the page where a page eject should be inserted.
This also controls whether Uniface will insert a form feed (non-blank value required) or default to the printer (blank value). It is recommended that you enter a value of at least 1.
