Statement Syntax, Explanation, and Input Instructions

Syntax and function of control commands are as follows:
wrt 705, "AP"
Automatic pen pickup command, "AP", causes plotter to auto-
m a t i c a l l y raise pen whenever it has been down without motion
for 65 seconds. This condition is set automatically when
plotter is initialized.
S e n d i n g , c h a r a c t e r s " A P O " to plotter will disable automatic pen
pickup.
wrt 705, "PD"
Pen down command, PD, lowers pen to paper.
w r t 7 0 5 , " V S 1 thru 36 [, Pen No.]"
Select pen velocity command specifies pen speed, in cm/see,
for plotting and lettering operations. Velocity can be any
v a l u e between 1 and 36.
If optional pen no. (1-4) is speci-
fied, speed will apply only to that pen. If pen no. is not
specified, speed applies to all pens.
Whenever plotter is initialized, pen velocity is set to 36
cm/sec.
wrt 705, "VA"
Sets plotter to adaptive pen velocity mode. Plotter will
a d a p t pen speed, automatically, to approximate rate that com-
puter sends coordinate data to plotter. This mode provides
smoother plot than normal velocity mode for plotting coordi-
nates that are generated by a relatively slow program routine
(fewer than 15 coordinates/sec).
wrt 705, "VN"
Normal velocity command, "VN", c a n c e l s a d a p t i v e v e l o c i t y m o d e .
P e n s p e e d i s n o w c o n t r o l l e d b y c u r r e n t p e n velocity command.
