Maybe someone here can help with one of these options:
- A self contained routine for bessel functions

Most Fortran programs are linked with the C libm,
so if you know how to call a C function, you might be able to use
the C entry. If your compiler supports the Interoperability
with C feature of the Fortran 2003 standard, it's actually portable
and not that hard.

- Some other idea?

As previously mentioned,www.netlib.org,
or see if you have a copy of Numerical Recipes,
which contains some Bessel routines.

If all else fails, try Googling for Bessel and Fortran!

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).
