Re: Order of function load matters ??

Yes. Order matters. I am sure someone more knowledgable than I
will answer more fully.

See slide 30? or so at
http://www.ncl.ucar.edu/Training/Workshops/lectures.shtml
"Data Processing" Power Point or PDF

Unlike a language like (say) fortran which has a compile/link/load
sequence where the linker sets up pointers to any callable
functions, NCL does not.

I think languages like python work th same way.
