It may be best to write your own version so that you could justifiably
have an accurate level of confidence of it.

!"It is in the Numerical Recipes in Pascal, chapter 6.4, pp 191.! 
 

!All you need to pick the right Pascal source, like bessj0.pas  ! 
 

!and put it through th P2Ada translator: http://p2ada.sf.net/   ! 
 

!The NR sources are freely available on the Internet."          !

I have not thoroughly assessed that particular part of "Numerical 
 

Recipes", but some parts of "Numerical Recipes" are
untrustworthy. Early in 2009 on
WWW.ACCU.org
a review by myself which is almost ready for publication should be
available.
