That works well ... but is there a way to pass that filename in
from the command line ?  I mean, if the csd has to be rewritten
every time, I'd want to do that automatically in a wrapper-script;
in which case I might just as well use Csound Power's p268 csd,
and detect the file-length using e.g.
  my $length = `soxi -D '$wav_file'`;
and rewrite the "e 3600" line accordingly, then invoke csound.
That would work with both -i rawfile.wav and with -i adc.

I understand that ins needs to return 0,0 after EOF, but it
would be nice if there were _some_ way of testing for EOF.
E.g. there could be a reserved variable gkEOFtime that I could
test, and if it's set I could schedule an appropriate exit...

Is there a way for a csd to detect what -i is being used ?

Thanks for your help,

hi peter -

as to this question:
"but is there a way to pass that filename in from the command line ?"

yes, you can set strset values in the command line, in the format
--strsetN=VALUE
so, for instance: --strset1='$wave_file.wav', and then just use '1' as 
input for diskin (or change back to a string via strget).

it might also be useful for you to work with the macro option:
--smacro:XXX=YYY
    Set score macro XXX to value YYY
as macros are executed first, it might be preferable in some cases.
