FILE= sends the output to the file associated with the fileref LABELS.
Because neither NDOWN= nor PAGESIZE= is specified, PROC FORMS uses continuous
mode. WIDTH= sets the width of the form units to 24 to provide enough room
for all the variables on each line. ACROSS= writes three form units across
each page. BETWEEN= puts four blank characters between adjacent form units.
DOWN= skips two lines at the top of the file so that the form units and the
forms align correctly. SKIP= skips two lines between form units to maintain
the proper alignment. ALIGN= prints two lines of dummy form units.
