Summary Of Dr. Logo Primitives - AMSTRAD cpc 6128 User Instruction

Occasionally, when nearly all the nodes are used up, Dr. LOGO will tidy up the
workspace and you may see the turtle pause while this happens. You can ask Dr.
LOGO to tidy the workspace by typing the command:
recycLe
This will often allow you to continue after Dr. LOGO has complained of not having
any more nodes left.
If you are using the CP IM 2.2 version of Dr. LOGO (on Side 4 of your master package),
make sure that there is plenty of disc space left before starting Dr. LOGO in case you
decide to save your procedures on disc. You can use the CAT command in AMSDOS
(see part 7 of the Foundation course) to see how much free space there is on a disc.
Now work through the following sections and try some of the examples - you won't
understand everything first time! As you learn about Dr. LOGO you will be able to
use more and more of the commands.
When you have finished with Dr. LOGO type:
bye
