Top Margin
Purpose The Top Margin command sets the distance between the top of
the printable area and the top of the text regardless of paper
orientation. The top margin is defined as a number of lines. The
height of the lines is determined by the Vertical Motion Index
(VMI) command, which sets the vertical spacing of lines. The
VMI is used as a unit of measurement for setting the margin, but
once set, the margin does not change with later VMI commands.
Syntax
E &l#E

#
is the number of the line on which text starts.
Example To set the top margin at six lines, enter:

Text Length
Purpose The Text Length command sets the number of lines on which
text may be printed. If the Vertical Motion Index (VMI) is zero, or
the sum of the text length and the top margin is greater than the
length of the printable area, the command is ignored.
