Hi Kendyl, 

There are two different concepts:

FIRST CONCEPT

a procedure that calls another procedure is a super procedure.
For example:

to procedureA
fd 10
procedureB
end

to procedureB
rt 90 fd 10
end

the procedureA is a super procedure because it calls procedureB.

I guess that a procedure that is so important that calls many other
sub procedures in your project is a super procedure and is also
THE master procedure.

SECOND CONCEPT

Things can happen (almost) at the same time in MicroWorlds.

For that
you don't need many procedures, you need many processes. a process
it launched using one of this:

- clicking on a turtle
- using clickon
- using "launch"
- using "forever"
- using "when"

so you can make different turtles do things (almost) at the same
time using:

to procedureName
launch [tto "t1 blablabla]
launch [tto "t2 blablabla]
launch [tto "t3 blablabla]
launch [tto "t4 blablabla]
end

avoid:

to procedureName
tto [t1 t2 t3 t4]
blablabla
end

because this solution does not work on PCs running Microworlds Pro.
