list_vars

Lists the currently defined variables that do not reference files or HLU objects.

Prototype

	procedure list_vars (
	)

Description

This procedure lists all of the currently defined variables, their types, and their dimensionality. If run at the command line, this procedure invokes a pager for scrolling through the list. The pager is either "more" or whatever the user's PAGER environment variable is set to.

Examples

Example 1

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

begin
;
; Read in netCDF file.
;
  a = addfile("$NCARGTEST/nclscripts/plotting/uv300.nc","r")
  u = a->U(0,:,:)
;
; Open a workstation.
;
  wks = gsn_open_wks("ncgm","gsn_csm_y")   

;
; Set some resources.
;
  res                        = True                        ; plot mods desired
  res@gsnMaximize            = True
  res@tiMainString          = "Example of gsn_csm_y"      ; title
;
; Create a plot.
;
  plot = gsn_csm_y(wks,u(:,30),res)

;
; Print the list of variables and their dimensions.
;
  list_vars()

end

The output from the list_vars call above is:

float   u [ lat | 64 ] x [ lon | 128 ]
        time
        _FillValue
        long_name
        short_name
        units

logical res [ 1 ]
        tiMainString
        gsnMaximize

Note that a, wks, and plot are not included, because these reference either files or HLU objects. See list_hlus or list_files if you want to list these.
