[squeak-dev] FileStream size limitation?

You could have gone the other way around! Like this:
| fs |
fs := FileStream fileNamed: '1-2729.rtf'.
oc do: [:each | fs nextPutAll: each asString].
fs close.
That way, regardless of the size of your collection, it will always work!

Subject: [squeak-dev] FileStream size limitation?
Hello,
I have an OrderedCollection with 24,576 elements.
A bunch of musical notes basically: each of the 24,576 elements is like:
#('eo6' 0.25 500)
for example.
Goal: I would like to turn that *entire* OrderedCollection into a single MIDI file.
However, there seems to be some sort of size limitation that I do not see how to get around.
1) Even before getting to the MIDI part, I tried:
FileStream fileNamed: '1-24576.rtf'
do: [:stream | stream nextPutAll: ((oc copyFrom: 1 to:24576) asString)].
which creates a nice file of 48.8KB size.
And opening the file, it ends with:
#('c#o6' 0.25 500) #('d...etc...
which is not what I expected.
2) If I do:
FileStream fileNamed: '1-2729.rtf'
do: [:stream | stream nextPutAll: ((oc copyFrom: 1 to:2729) asString)].
it works fine: ending tidily with the expected:
#('c#o6' 0.25 500))
3) But,
FileStream fileNamed: '1-2730.rtf'
do: [:stream | stream nextPutAll: ((oc copyFrom: 1 to:2730) asString)].
is where this starts:
#('c#o6' 0.25 500) #('d...etc...
This exact same problem happens when making MIDI files: there seems to be a size limitation around 48.8KB.
Aside from MIDI, is FileStream just the wrong class to use for anything larger than creating a 48.8kb text file (.txt or .rtf)? Or how can I get around this restriction?
Any suggestions are most welcome.
Thanks,
ken
