[ncl-talk] Problems reading monthly files with systemfunc

[Rick Brownrigg]

Hi,

NCL is strongly typed in the sense that once a variable is defined with
certain dimensionality, that becomes part of its "type". The solution is to
use the "re-assign" operator:

   file1 := systemfunc(....)

which is short-hand for

  delete(file1)
  file1 = systemfunc(...)
