dear GrADS users,
     In a grads script I compute four parameters and
want to write all the four to an ascii file as
follows.


(a)         (b)          (c)          (d)
--------------------------------------------------
Var(1,a)    Var(1,b)     Var(1,c)     Var(1,d)
Var(2,a)    Var(2,b)     Var(2,c)     Var(2,d)
..................................................
..................................................
Var(n-1,a)  Var(n-1,b)   Var(n-1,c)   Var(n-1,d)
Var(n,a)    Var(n,b)     Var(n,c)     Var(n,d)


--------------------------------------------------
and i want to call a value from the column (d)
corresponding to the value in column (c) OR (b) (in
the same row). A fortran code to write the data as i
want is given below

***************************************************
        do 30 k=1,n
        c(k)=fn(k)
        p(k)=fn1(k)
        a(k)=fn2(k)
        w(k)=fn3(k)
        write(*,40)c(k),p(k),a(k),w(k)
30      continue
40      format(f7.4,1x,f8.4,1x,f15.4,1x,f15.4)
**************************************************

   i want a similar operation in grads and then to
call a value from one column according to some
threshold
values in another column. i hope this would
communicate my need.
thanks
suha
