And, in addition to this, there's a good chance that Bessel functions et al. will be intrinsic functions in Fortran 2008 (which will be the Fortran Standard after 2003 has gone out succesfully - a paper exercise if there ever was one ... ;-) -- Toon Moene - mailto:toon@moene.indiv.nluug.nl - phoneto: +31 346 214290 Saturnushof 14, 3738 XG Maartensdijk, The Netherlands Maintainer, GNU Fortran 77: http://gcc.gnu.org/onlinedocs/g77_news.html A maintainer of GNU Fortran 95: http://gcc.gnu.org/fortran/
