if you wanted to employ this syntax you could "upgrade it" :-)  to:
run (word :thisturtle ", char 32 "clickon)
which actually works, but is a mite deliciously warped

try instead the simpler

to roulette
   make "thisturtle pick [turtle1 turtle2 turtle3 turtle4 turtle5]
   ask :thisturtle [clickon]
end

By the way, our earlier glitch with the duplicated turtles across pages
was solved when we discovered that the WHEN-TOUCHING code stopped
(entirely on its own) when we went to a new page.&nbsp; And to think that
I'd spent a week drilling in the fact that asking MicroWorlds WHEN was to
be done once and only once!&nbsp; When we called this procedure (of
WHENs) again after arriving at the second page, the game continued
okay.&nbsp; Is this really the way it works?&nbsp; I'm still quite
surprised.
