Thanks everybody. I found something in calgo that might help, it's the
same subroutines from the slatec library but at least they are
together in one file. I already spent too much time trying to get this
library to work, but I'll keep trying because it's the only open
source fortran library with bessel functions (Numerical recipes
doesn't include the general case of complex argument and fractional
order).

A Portable Package for Bessel Functions of a Complex Argument
and Nonnegative Order

This algorithm is a package of subroutines for computing Bessel
functions and Airy functions. The routines are updated
versions of those routines found in TOMS algorithm 644.

Thanks Steve. I did look at the Amos package earlier and I think I can
make it work, although it doesn't compile "out of the box" (the rmach1
and imach1 functions are missing).


Search netlib for the routines. They are there somewhere.
