I was not aware of this limit.  I don't see it in the limits page of the user guide for LiveCode 5.0.2.

I have not had trouble passing very long strings as parameters, though often, if that is likely, I set up the handler to require a referenced variable for speed.

Is this a limit in the number of parameters?

Is this driven by the maximum length of a line in a field?

I'd like to get a better handle on this in my mind, so any clues you have would be good.
