Each of these devices is described in a section of this chapter. The SET_PLOT procedure can be used to select the graphic device to which IDL directs its output. IDL Object Graphics does not rely on the concept of a current graphics device.

The DEVICE procedure controls the graphic device-specific functions. An attempt has been made to isolate all device-specific functions in this procedure. DEVICE controls the graphics device currently selected by SET_PLOT. When using DEVICE, it is important to make sure that the current graphics device is the one you intend to use. This is because most of the devices have different keywords—you will most likely get a ``Keyword ... ... not allowed in call to: Device'' error if you call DEVICE when the wrong device is selected.
