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).
