Hi Patrick, I've packaged a pre-release version of Inline::BC 0.08.
It is available from: http://au.geocities.com/rongrw The package includes the sample Perl file "sinhcalc_c.pl", which I use primarily to test the new version. Cheers, Ron.

Is there anywhere I can get Inline::BC 0.08 to try it out?
