Bugs That May Have Been Fixed
Bug: (316, 48) : ERROR Syntax Error
The thousand lines of Chatbot script is script enough to confuse some compilers.
The LSL Write Once Debug Everywhere article explains how you can develop LSL scripts that run well and compile without error in many places.
The LSL Errors article explains the astonishing 2007-08 Windows compiler limit of about a dozen cascaded else-if's (astonishing when contrasted to the Mac limit of about five hundred).

Rethink
I have by now thought thru a new design for ducking our ill-defined not-quite-cross-platform-reproducible script resource limits by dividing the work out via llMessageLinked.
Sorry as yet I'm thinking in the deeply geeky slang of compiler folk. Out in that world, my thinking runs as follows.
http://members.aol.com/ppaatt/#%5B%5BReverse%20Polish%20LSL%5D%5D is my definition of Reverse Polish LSL. I figure we want to chat ordinary LSL onto a channel, then see (forward) Polish chatted on a channel. In translating from ordinary LSL, we'd chat the depth-first Polish first, i.e., the leftmost ( ... ) found, with just values as parameters. We'd then see the result chatted on a channel, which will let us form the next expression out.
I plan to head that way here as soon as I get some more time slices free to work this. That way will let us divide the else-if's arbitrarily into indefinitely many functions.
I figure we can define monadic == to mean evaluate a name.
I figure we can use simply-quoted URL-encoding to pass strings around.
I figure we want to distinguish no result, void result, non-list non-void result, possibly-empty list result. I figure we count the "no results" til we have enough, to know when no one listening can make sense of the Polish LSL that was chatted.
