SM - Symbol Mode
SM c [;]
c ; ASCII character or symbol code
• The command specifies the symbol to be drawn.
• The specified symbol will be drawn at the end of each vector, irrespective of whether the pen is up or down,
when the PA, PR, PD, PU or PE instructions are used.
• Characters in the character code ranges 33 - 58, 60 - 126 and characters 161 and 254 can be used.
• Character code 59 stands for the ';', which is the HP-GL/2 terminator. You cannot use it as a symbol.
• The current character size, slant and direction settings affect the way the symbol is drawn.
• Omitting the parameter cancels the symbol mode.
• On quitting symbol mode the original pen up/down state is restored.
SP - Select Pen
SP [ n ] [;]
n ; pen number
• The command selects a pen for drawing.
• You must use this command before performing any drawing or filling commands.
• n should be either 0 or 1 ( although any other integers will be interpreted as 1.)
• If n is 0 the white pen is selected. In this case drawing commands will have no effect, unless you are
plotting onto a dark background and transparency mode is off.
• If n is 1 the black pen is selected and printing can proceed normally. Use SP1; at the start of HP-GL/2
programs.
• Invoking the command with no parameter is equivalent to SP0;.
