|'send Next to this card' no longer works because the word 'next' is a
|keyword in HyperTalk, and keywords can no longer be sent as messages.
|(I'll leave it to Dan Winkler to provide an explanation of why this
|is so, perhaps in his next book.)
|
|Here's the complete list of keywords:  do, else, end, exit, function,
|global, if, next, on, pass, repeat, return, send, then.  If you have
|handlers with any of these words as names, you won't able to invoke
|them in 2.0.


I think the list of words you can't use as messages is a little longer.
For example, my buddy and I had trouble with an 'on div' handler
and a variable named 'me', both of which came from a working 1.2.x
stack.  My suggestion is to avoid *all* HyperTalk words to avoid
hassles.
