At present time an 'fclose' opcode doesn't exist yet. So, each time a
new file is created, it will be written continuously up the end of
Csound session. However now it is possible to pass string arguments by
the score, so it is possible to write more file, opening them at
different times. It is not good for realtime performances. Also, a
string manipulation opcode doesn't exist, so the filenames must be
already defined by the user as string constants at the orc/sco design
time. So, for now, you have to do this task manually, editing the wave
files generated afer the realtime session by means of a wave editor
(such as Cool Edit).
