Comment on editing front scripts

[MisterX]

we do have to look at the scope we need.

Debugging, variables, script editor, error display (and relevance to error
or compilation problems), etc... 

And there is the hierarchy of problems when a function calls one which has a
mistake as you pointed out before (an old problem!)... 

Part of this problem is the lack of threading in the engine imoho. Different
threads that dont interfere or block the others would be quite helpful! It
would require a few "trys" and catches more but it would solidify things
further. HyperCard has a separate code running to do debugging and script
editing and surely that helped a lot more than having an all in one script
environment that does the IDE operations and debugging at the same time. 

As I've said before the IDE interferes a lot, and the issue comes back again
and again in one form or the other... 

If it helps, here's some rules and logic operation schemes from XOS:

For one, I keep track of who locks and unlocks what and in what order (FIFO
style). 
If one operations blocks the other, there's either a debug breakpoint with
data report (customizable report of who did what when with what data) or
there is an overrule of a lock (uninplemented yet). 

One intersting adventure I had is this:

You know the errordisplay is GM broken each time an error occurs (where's
that revOnline update i wonder). But the RevVariableWatcher uses a
resizestack handler. I tried to improve the RVW because of it's totally
annoying resizing inneficient design and adding Rev's GM features was total
chaos in the engine! I had to restore an virgin copy of the RVW to continue!
;)

So, separation of tasks via threading (for non-data-returning handlers)
would be cool and a solution to Rev's error-handling erratic display... 

As soon as my mom leaves, I'll start working on the GM for XOS now that the
XOS Language engine is near finished.

It's hard to develop an IDE, that's for sure! But all together it's that
much easier!
