Is this fault the same when using OS X or does OS X handle
read command differently?

You'd get the same error running the script from an
applet. It's a
limitation of the 'read' command. It's limit must be far
higher than the
30,000 bytes I'm using, but I don't know what it is, and
30K always works.
Since the read command is extremely fast, breaking it
into chunks this size
still doesn't take much time and is safe. I'm open to
hearing from anyone as
to a higher number of bytes that's guaranteed to work
100% without error.

OK, I see, I had some similair idea of splitting the
file
in my head, but I thought that it must be possible to
read
the whole file at once. But I guess its not possible,
right? Is this due to limitations the script editor
itself?

I'm reading a file from disk which is about 1200 lines

this error telling me "stack overflow" when reading

files, smaller files are reads ok though. Is there a way
to control memory in AS or is it just a lack in the
script
editor (1.8.3 under OS 9.2.2)? Any workarounds for this
kind of problem?
read my_xmlfile as string to eof --reads the file
set fileRef to open for access alias "file:path"

set b to 1
set y to 30000

repeat until finished
try
set textClump to read fileRef from b to y
set r to r & textClump
on error -- last text clump
set textClump to read fileRef from b to eof
set r to r & textClump

end try
set {b, y} to {b + 30000, y + 30000}
end repeat
return r
end ReadPartials
