The language sold under the name "Color Logo" for the Color Computer
lacks lists and many of the things that go into Logo, but it's still
a neat hack and worth considering for teaching the young to program.

What it does that is particularly slick (and provoked this note) is
the multitasking facilities it provides, via the command

	HATCH <name to give turtle> <command and parameters>

which creates a turtle with the specified name (well, a number
between 1 and 254) which is assigned the task of executing the
specified procedure. Turtles can send one another mail (well, a
16-bit two's complement integer) (not to mention sending mail
"to whom it may concern," which is read by the next turtle that
tries to read mail).

I DO hope that the developers of Color Logo will consider expanding
the language now that they have OS-9 and more memory to play with...
