FILE= sends the output to the file associated with the fileref LABELS. NDOWN= prints five rows of form units on each page. CC writes carriage control characters to the file specified by FILE=. ALIGN= suppresses the printing of dummy form units. WIDTH= sets the width of the form units to 24 to provide enough room for the variables on each line. ACROSS= writes three form units across each page. DOWN= skips two lines at the top of each page so that the form units and the forms align correctly. SKIP= skips two lines between form units to maintain the proper alignment. COPIES= writes three copies of each form unit.
