NOTE
Some symbols in the following text are not else-
where defined in this manual.
Refer to Hewlett-
P a c k a r d operating manuals for complete symbol
definitions.
Symbol mode command, "SM", is used with PA and PR commands and
p r o v i d e s the means to draw a symbol at the end of each vector.
S y m b o l is limited to a single character and may be any print-
i n g character except: (ASCII 59). PA and PR commands function
as usual, except that the specified character is drawn at the
end of each vector and is centered on the plotted point.
C h a r a c t e r will be drawn at the end of the vector whether the
p e n is up or down.
C h a r a c t e r is drawn according to the
character set currently selected when the SM instruction is
executed.
Once selected, the character is independent of
character set changes later in the program and can only be
changed by a new SM command.
If a character is not specified
the symbol mode is cancelled. If a non-printing or control
character is specified, error 3 is set and the symbol mode
is cancelled. The size (SI and SR), slant (SL), and direction
( D I and DR) commands affect the character drawn. An SM com-
m a n d remains in effect until another SM command is executed
or the plotter is initialized or set to default conditions.
S i n c e symbol mode can only be used with a single symbol, when-
e v e r a label requires more than one symbol, CP instructions
must be used.

by axis statements. Tic lengths are specified as percentage
of horizontal and vertical distances between scaling points P1
and P2.
Up
and right tic length determines length of upward portion of
tic
marks to be drawn along X-axis and right side portion of
tic
marks to be drawn along Y-axis. This value is specified
