Meanwhile, I managed to express the data of a 32-bit big-endian two's
complement integer as a sequence of 4 characters. But you are
probably right: I have to re-do the job and it rather inefficient..
Problem is only my shaky C programming experience ;-)

I would solve this by finding an implementation in C (googling for
osc implementation gives me this: http://liblo.sourceforge.net/)
and then write an interface to OZ. That's usually easier than doing
everything yourself. In this case you get the added bonus of being
able to cast between 32 bit and 64 bit values whenever you need.

Dear all,
currently, I am trying to talk to other applications via some
communication protocol (more specifically, it is OpenSound
Control, see http://www.cnmat.berkeley.edu/OpenSoundControl/). The
syntax of this protocol requires that I send/receive data of
formats such as 32-bit integer (big-endian) and 32-bit floats (big-
endian). The communication itself happens via sockets.
Oz floats are internally 64 bits (according to CTM). Their print
representation (Float.toString) is less, but not fixed in size
(BTW: it does not use Oz syntax, the negation sign is - instead of
~). Oz integers can be of any size. I assume BitArray or BitString
don't help me either, because I can not output them. Also,
ByteString is intended for textual data.
Any idea how I can control the size of integers and floats send
across a socket?
Thank you!
Best
Torsten
