Dear Lisa,
the PAGELIST reporter always identifies the page you're on, by stashing it 
in the first position on the list
Capitalizing on this, you can create a homespun reporter to extract that 
information wherever you are:

to thispage
op first pagelist
end

Analyzing the value of THISPAGE, you can now merrily, 'IF_THEN' your way to 
one of any of several routines.

Here's an even more interesting variation:

If you renamed your pages Level_01, Level_02, Level_03, etc, then you could 
rename the THISPAGE reporter, GAMELEVEL and modify it slightly
to return just a level number. Numeric values would prove valuable if one 
or more level ranges share common strategies.

to GAMELEVEL
op bf bf bf bf bf bf first pagelist  ;(works only when stripping away the 
first six characters of the page)
end

that want to design &quot;levels&quot; to their games.&nbsp; Basically,
this means that when their player has accomplished the goal on one page,
they take him to a new one where the action continues with a similar
challenge...just a bit more difficult/complex. 
My question has to do with the turtles...and particularly their names and
the procedures which affect them.&nbsp; MicroWorlds allows you to create
multiple pages which contain the same turtle (names).&nbsp; This is what
we'd like, of course, because the core of the game logic will be used
across pages (our &quot;levels&quot;).&nbsp; However, we've run into
difficulty.&nbsp; Understandably so, I suppose. For example, how is
MicroWorlds to know which of the CAR turtles it should work on when
there's one on page1 and page2?&nbsp; My assumption would be that it
would affect the one on the active page only.&nbsp; But this doesn't
appear to be correct. MW appears to be ignoring the turtles on the second
page. 
Is there something we're missing?&nbsp; Is it even possible to have two
turtles (with the same name) on separate pages utilizing the same
code?&nbsp; If not, could you share any tricks to get this concept
working without duplicating code?&nbsp; (On option would be to use
variable input to the procedures and pass in the turtle name, but even
this would require reworking what they've already designed and tested.)
 
Thanks a million for any suggestions.
