Thanks a lot of the great info.
I'd found the environment variable is GMX_NB_GENERIC.
By setting this, my modification code was activated and the LJ potential
outputs were turned from negative to positive values (since the LJ was
truncated till its repulsive part).

For this, I still could not figured out.
The variable eNBF_NR limits the case number in the routin topio.c, but
I could not find how the variable was defined.
I'll try more.
Thanks a lot again.
