The keyboarder can easily center material horizontally
when a word processor is used.  Usually, this involves only
a single line in the document and the material is correctly
centered with a single keyboard command.  However, at times
there does exist a need to center several lines of material
simultaneously.  When using Simple Writer the several lines
of copy must first be marked with a block command to ensure
that the centering command involves only the specific lines
that the operator wishes to center.  After a marked area is
centered the unmark command is employed to unmark the copy.
     Simple Writer permits the automatic vertical centering
of text material.  If the data is to be vertically centered
on a full page, the keyboarder may position the material at
any vertical point on the page.  After the lines are keyed,
or entered, the vertical centering command instantly places
the material on the page with equal top and bottom margins.
Centering on a half page or any vertical area less than one
page demands that the area's beginning and ending points be
marked.  Once the vertical centering command is executed to
center the lines, the marked area is removed from the page.
