Data Processing Examples

• NCL uses an array syntax similar to Fortran-90.
• NCL has 0-based subscripts and the rightmost subscript varies fastest.
• Fortran has 1-based subscripts, and the leftmost subscript varies fastest.
• Do loops should be avoided, since NCL, like Matlab and IDL, is an interpreted language.
