[ncl-talk] copying resources from one set to another --> ?

Tue Nov 7 16:03:01 MST 2017

Barry,

Since variables are not overwritten unless you do a ":=", you can do this
kind of thing:

 opts_xy = True
 opts_xy at xxxx = ....
 opts_xy at yyyy = ....
 opts_xy at zzzz = ....

  opts_rad = opts_xy
  opts_rad = set_res1_list()

and opts_rad will have the resources from both opts_xy and set_res1_list.

Try this program to verify it:

function set_res1_list()
begin
  res = True
  res at gsnMaximize      = True
  res at xyLineColor      = "red"
  res at xyLineThicknessF = 2.0
  return(res)
end

begin
  opts_xy = True
  opts_xy at gsnDraw = False
  opts_xy at gsnFrame = False

  opts_rad = opts_xy
  print("==================================================")
  print("First time")
  print(opts_rad)

  opts_rad = set_res1_list()
  print("==================================================")
  print("Second time")
  print(opts_rad)
end
