[ferret_users] how to change the value of the variable in Ferret?

["Xia Changshui" <xiacs@xxxxxxxxxx>]

Dear all,

 

I have a simple qusetion, I have a netcdf format file, the variable in it is H(100,100) , I want change the value H from i=50 to 60, j=50 to 60, how to achieve this?

 

in fortran it is very easy

 

  for j=50,60

for i=50,60

 h(i,j)=h(i,j)+5.0

enddo

enddo

 

but how in Ferret?

 

Thanks
