PDF error

Dear NCL users,

I'm using an simple example of NCL for plotting a contour map into a PDF
file. The script is below

*load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
begin
 c = addfile("Download/uv300.nc","r")
 u = c->U(1,:,:)
 wks = gsn_open_wks("pdf","campo1")
 plot1 = gsn_csm_contour_map_ce(wks,u,False)
end
*
When I put this script into a file, it works perfectly, generating a PDF
file. But, when using NCL in interactive mode and typing each of these
lines, and not leaving NCL's interactive environment, I can't open the PDF
file.

Using the diff command to see if there are differences between these two PDF
files I saw that the file generated with the script had 45 additional lines,
given below

The PDF file generated from inside NCL's interactive mode only will have
these same lines when I quit NCL or delete the workstation variable.

I would like to know if it is a correct functioning of NCL. If so, I would
like to suggest this information being included in gsn_open_wks
documentation, once an user may think some script he/she's typing inside NCL
is wrong.

Best regards,
