Dear Colleague:

I am glad to hear from you. I was going to contact you and ask if you have 
notes on the steps involved on how you implemented LSODA. I will gladly take the
project on. In addition to dassl, I want to implement ODESSA also. In other 
words, my project is a "suite" of ode solvers for R. The application
of these
solvers will be to the study of the distribution of radioisotopes in living 
systems in diseases such as heart failure, diabetes, aging and high blood 
pressure.

I have been toying with the latest g77. I find that it does not compile
"out
of the box" fortran IVP solver codes (ACM transactions ode solver codes). 
However, the COMPAQ Visual Fortran (cvf) 6.6B compiles the object code without
any
errors.

I plan to work with Windows XP and 2000, cvf, and the latest R. I found that 
Prof. Ripley's S programming book and the BLUE book are very helpful. I have
alreadychecked the r-archives and it has not been helpful.

So, any notes on the procedure will be much appreciated.

Kind Regards,
