[gmx-users] questions on topology files

We are trying to understand the topology files a little better, but don’t
understand some of the layouts.
1) In ffG43a1nb.itp there is a field know as p-type under the section
[atomtypes] whose value is typically “A”. What is this value?
2) In ffG43a1.rtp, under the heading [atoms], what is the last number after
what appears to be the charge?
3) Finally, I have heard that Gromacs supports exponential type van der
waals potentials, but I don't see how to enable or disable this. Or how to
use Lennard-Jones instead, etc.
Any help would be appreciated.
