temp bat is
csound temp.orc temp.sco
and it plays the new files I can try closing the other files first. I
am sure the readlines code is crashing it. Because I have moved it
befour the code that is reading a line at a time and it would not even
write the second zero byte file. The comment line is an old line that
I did not update when I made changes. The code that calls it was
auto-generated but boa-constructer .44 (I haven't updated it yet).
