Hi Dave,
You beat me to it. I was about to suggest the same change and was iterating
through what is used in the subroutine to see what is needed in the 'only'
statement.
It looks good to me. Although I was also looking to add the only flags to
all the 'use prmtop_dat_mod' in the pme_setup.fpp file but that takes a
while to find things. If your simple fix works then we might as well just
update those lines for the moment.
All the best
Ross
