[Coco] D.L. Logo question

[Robert Gault]

Let me start by saying I don't know the Logo language and never used it 
until the following occurred.

I was given a disk image of what I believe is the original D.L. Logo 
disk for OS-9 Level-I. The disk contains a Demo program and several data 
files that are part of Demo. I been testing the disk image in MESS and 
the odd thing is the program won't run as written; Out of Memory Error.

If this program was supplied with D.L. Logo, it is strange that it won't 
run as written. The best I've been able to do is start Logo as follows:
logo #24K
After boosting data memory (default is about 10K) the program will at 
least run a single pass to completion. However, the program is written 
to repeat in an endless loop. With 24K, the program runs out of memory 
on the second pass. I've not been able to give logo more memory nor get 
the program to run through more than one pass.

Can anyone owning D.L. Logo provide information on the above? Were there 
instructions in the owner's manual on increasing the amount of memory 
available to Logo? Is there some garbage clearing command for Logo which 
should be used in the program after each pass?

It seems to me that the demo program chews up data space with recursive 
routines. I've no idea if Logo has memory flooding or what it does to 
clear data memory when a recursive program ends (if necessary).
