TURTLE TUTOR
by Captain COMAL
Just for you! Included on this disk
is a complete Logo compatible Turtle
Graphics System. Yes, Logo Turtle
Graphics are built into COMAL, and
the full COMAL 0.14 system is on this
disk. Since turtle graphics may be
new to you, we have included an
interactive tutor system. It will go
over the various turtle commands that
are included with COMAL. It will
present each keyword, its syntax, and
an example of how to use it. Even
better, it will demonstrate its use
in the center of the screen.
Next month, we will include a
graphics tutor system. It will
present all the other graphics
commands that are available with
COMAL. Until then, try out Turtle
Tutor. Then test out the commands for
yourself. Stop the Turtle Tutor
system. Then issue these commands:
setgraphic 0
splitscreen
forward 30
left 90
forward 30
etc...
Have fun. For other turtle examples,
see the program DESIGN also on this
disk.
