I remember someone saying that "before" was the most taxing to the engine.
It is so, and the point where things go south occurs much sooner. Whereas the
slowdown takes place at a million plus with "after", the slowdown happens
between 10,000 and 100,000 with "before":
on mouseUp
put "XXX" into temp
put the ticks into s
repeat 10000 -- (10,000) about 25 ticks. But a minute with 100,000
put temp before accum
end repeat
answer the ticks - s
end mouseUp

Geoff,
Is 'put "something" BEFORE myVariable' quicker? That way, the engine doesn't
have to track to the end each time.
Just an idea.

can't see what. :-/

...okay, I won't bore you all with the details. The tl;dr is that this:
put "something" after myVariable
is very fast, but gets slower the bigger myVariable becomes. I'm slinging
around 100s of MBs, and LC doesn't really like appending strings to a 300mb
variable...
I have to change to read from my input line by line anyway, and I'll write
to my output the same way, and all the variables will be much smaller then.
Thanks for listening
