ask a question when using "reshape"

Hi Everyone,

When I try to transform a 3D matrix to 4D matrix, I plan to use "reshape". But even for a very short test script it always give me the wrong message.

The test script is from the website https://www.ncl.ucar.edu/Document/Functions/Built-in/reshape.shtml

;************

;test for reshape
;*****
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
;******
begin
x= random_uniform(-100,100,(/10,20,30/))
x2d = reshape(x,(/200,30/))
print(x2d)

end
;****************

the error message is :
