It is a bit over-the-top with module usage but it gives an idea of how to proceed. To my knowledge, modules *must* be compiled before they are used. Hence, the ordering on the WRAIT example.<br><br></div>Since NCL's WRAPIT is f77 aware (*not* f90 aware), any f90 subroutine invoked from an NCL script must have an associated 'stub' file which uses f77 syntax.
