Re: 20040813: Adding a subroutine

Thanks Steve!

My next question is:
In oabarn.f,
my new weight is
wt = EXP (-dsq*wtfac - dtq/ctau**2 )
where ctau is the new command line arguement
but dtq depends on that particular station's STIM variable.
where STIM will be different from the analysis time.
STIM is going to be a variable in my surface file.

How do I get STIM to the barnes routine without analyzing it?
I don't follow how the data is sent between oabsfc.f and oabarn.f
Thanks again...
