Re: LOGO-L> microworlds program question

["Gary S. Stager" <logoexchange@moon.pepperdine.edu>]

Hi,

I need to know more specifics about his project to make a definitive 
prescription, but based on the symptoms, let me suggest the following.

Recursion is hard to stop and often gets confused with the parallel 
nature of MicroWorlds.

He may need to rethink how the program works. He may not need recursion 
here at all. If he does need recursion, he could use a counter in it to 
check IF :COUNTER > 8 [STOP page2]

Otherwise, he could consider using REPEAT 9 [blah blah blah]

OR... if each turtle is running an instruction, you can use CLICKON to 
start the process and ask [list of turtles] [CLICKOFF PAGE2] to stop them 
and continue on to page2.

You do not need to use GETPAGE to change pages in MicroWorlds. Just the 
pagename will do as a command unless you need to input a different name 
from time to time as in, GETPAGE :thenameofthepagetheuserwantstogoto

Hope this helps!
