This command specifies left and right margin positions. The n
1
and n
2
parameters
indicate respectively the number of columns for the left and right margins at the
current spacing. These margins are memorized in terms of absolute displacement from
the physical left edge of the page.
If n
1
is equal to 0, the current left margin of the page is used. If n
2
is equal to 0, the
current right margin of the page is used. The left margin value must be less than the
right margin value. The right margin value must not exceed the physical right edge of
the paper; otherwise the maximum acceptable value for the right margin will be set.
