Re: loading contributed.ncl in a where document fails with ncl 6.2.0

Keith,

We are going to look into this right away. A work-around is to put the "load" command *before* the "begin" command. This is generally recommended anyway.

I think this has to do with the fact that with V6.2.0, the gsn_code.ncl, gsn_csm.ncl, and contributed.ncl scripts are all loaded automatically. That is, you don't have to do:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

anymore. We purposely didn't advertise this, because it still works fine if you load all those scripts, and we weren't 100% sure how well it was going to work if people stop loading them.

So, you have two work-arounds:

1) Move the "load" command before the "begin" command.

2) Use "loadscript" and only load the script if you are running NCL V6.1.2:

ncl << EOF

begin
  if(get_ncl_version().eq."6.1.2") then
    loadscript("$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl")
    print("Loading contributed.ncl...")
  else
    print("NOT loading contributed.ncl...")
  end if
end
EOF
