setmargins
SETMARGINS vector
command. The input must be a list of two numbers, as for
SETCURSOR. The effect is to clear the screen and then arrange for
all further printing to be shifted down and to the right according
to the indicated margins. Specifically, every time a newline
character is printed (explicitly or implicitly) Logo will type
x_margin spaces, and on every invocation of SETCURSOR the margins
will be added to the input x and y coordinates. (CURSOR will report
the cursor position relative to the margins, so that this shift will
be invisible to Logo programs.) The purpose of this command is to
accommodate the display of terminal screens in lecture halls with
inadequate TV monitors that miss the top and left edges of the
screen.
