SY.
The SYMBOL statement draws a graphics pattern of a given size at a given angle.
When this statement is encountered, BASIC positions the lower left corner of the
graphics pattern represented by <text data> at point (X-coordinate, Y-coordinate),
rotated by <angle code>, and magnified by a factor of <horizontal magnifica-
tion> and/or <vertical magnification>.
The meanings of the <colour specification> parameter are identical to those of
the SET statement. When this parameter is omitted, the parameters in the COLOR
statement are assumed.
The range of values that < X-coordinate> and < Y-coordinate> can have is iden-
tical to that specified in the SET statement. <horizontal magnification> and
<vertical magnification> are integers from 1 to 255 and default to 1.
When <angle code> is specified, the pattern is rotated counterclockwise with respect
to the upper left corner of the pattern at point (X-coordinate, Y-coordinate) by the
angle specified by <angle code>. The reference position of the pattern remains
unchanged after the rotation. The relationship between angle codes and angles is
given below.
