Aspect ratio parameter specifies ratio of height of character
to its width.
For example, an aspect ratio of 2 specifies
characters that are twice as high as they are wide. An aspect
ratio of 1 specifies square characters.
Paper ratio parameter specifies ratio of height of scaling
area to its width.
Scaling area is defined by scaling points
P1 and P2.
F o r example, 10 in. (25.4 cm) high X 15 in. (38.1
cm) wide scaling area has paper ratio of 10:15 or 2:3.
Angle of rotation parameter specifies direction in which char-
a c t e r s a r e p r i n t e d . Direction is expressed as angle (measured
left) between line of print and X-axis, as shown below.
Parameter is expressed in current angular units (degrees,
radians, or grads).
Default values for four parameters are as follows:
1.5%

2

Executing csiz statement without parameters sets default
values.
These values are also set when plotter is initialized
or cleared ( p c l r ) .
T h e f o l l o w i n g e x a m p l e p r o g r a m u s e s c s i z instruction (line 3)
to specify character dimensions and shape and rotate lettering
direction through entire circle in 10-degree intervals. Plot
statement (line 2) centers pen for each printing sequence.
