As an owner of the Numerical Receipes in Pascal, I can say that the sources codes are *very very old* 
styled and a rewritting to dynamical array of data is a good idea ! The N.R. are probably written by 
ForTranists :) But ths book contains lots of useful knowledge en tricks for numericians and is pleasant 
to read.

Cheers, Ched'
