Dear NR team,

I would like to use the Kaps-Rentrop parameters for the routine stiff. The
source code in the cd-rom (Unix version 2.06) contains the
Shampine parameters only.
I amnot able to find them on the cdrom.
Just to avoid the manual typing (errors can be
made!) I would like to know if is possible to have a file with the Kaps-Rentrop
parameters (page 741 of the book v2.06).

Regards
