Hi Francois,
I guess I am having difficulty understanding your
previous E-Mail since I am not experienced on the
freezing stuff you mention

RMS values at the end of Output 1:
---------------------------------------------
Statistics of the fitting:
The initial sum of squares (ssvpot)
161.277
The residual sum of squares (chipot)
0.015
The std err of estimate (sqrt(chipot/N))
0.00433
ESP relative RMS (SQRT(chipot/ssvpot))
0.00973
-------------------------------
RMS values at the end of output 2:
Statistics of the fitting:
The initial sum of squares (ssvpot)
161.277
The residual sum of squares (chipot)
0.015
The std err of estimate (sqrt(chipot/N))
0.00433
ESP relative RMS (SQRT(chipot/ssvpot))
0.00973
------------------------------------
Are these values good?

Here is a part of input 1:
1.0
c4w
1 13
8 0
1 0
1 2
8 0
1 0
1 5
8 0
1 0
1 8
8 0
1 0
1 11
29 0
Ok. What do I do here for the O and H equivalencing
you mentioned?
> - Freeze all in input2
Here is a part of input 2:
1.0
c4w
1 13
8 -1
1 -1
1 -1
8 -1
1 -1
1 -1
8 -1
1 -1
1 -1
8 -1
1 -1
1 -1
29 -1
Again, what do I do to freeze stuff here ? add zeros
intead of -1?

Manually in a gamess input? which one? How?

I guess it would be a good idea to have a beta version
of REDIII sometime from you.
