Although an ascii interface can work to call sub-routines, it has
limitations for smooth control of a robot when operating in a closed
loop system, where 256 bit resolution is required at a 30 Hz update
rate. Furthermore the ascii byte has to be deciphered in script code,
which as we know is slow on the oopic.
Another advantage of SCP is that it runs in the background with no
effect on the object list speed when virtual circuits are being used.

SCP in my opinion is easy to use and is very slick. A few years ago I
wrote a GUI terminal for SCP which is available in the files section of
this group. The package is called SCP-Configurator and makes working
with SCP a pleasure without the sweat of having to refer to chapter 16
of the Oopic manual.
