You might want use the GET_SCREEN_SIZE () function
instead, as it won't crash if the device is
not set "properly":
IDL> PRINT, !D.NAME
X
IDL> DEVICE, GET_SCREEN_SIZE = s & PRINT, s
1024 768
IDL> s = GET_SCREEN_SIZE () & PRINT, s
% Compiled module: GET_SCREEN_SIZE.
1024.00 768.000
IDL> SET_PLOT, 'PS'
IDL> DEVICE, GET_SCREEN_SIZE = s & PRINT, s
% Keyword GET_SCREEN_SIZE not allowed in call to: DEVICE
% Execution halted at: $MAIN$
IDL> PRINT, !D.NAME
PS
IDL> s = GET_SCREEN_SIZE () & PRINT, s
1024.00 768.000
IDL>
