Just as an aside (nothing to to with the problem, but with the work-around)

We've done several of those "executable NCL scripts" using a general
wrapper to ncl that allows to use ncl the same way as any other script
language, passing --option=value as an NCL variable "option" and
positional parameters as an "ARGS" array. Our wrapper is called nclsh
and uses perl (see gzipped attachment) - there might be other ways to do it.

With that unpacked into a directory, say, /your/home/bin, you would
write "ncl_filedump.ncl" simply as

  print(addfile(ARGS(0),"r"))

and define your alias like

  alias ncl_filedump="/your/home/bin/nclsh /path/to/ncl_filedump.ncl"


Alternatively, you could write a "/your/home/bin/ncl_filedump" as

  #! /your/home/bin/nclsh
  print(addfile(ARGS(0),"r"))

make that an executable script (chmod +x) and - for bash - do

  PATH=/your/home/bin:$PATH

Best,
Karl
