DOPEN
This opens a graphics display device and makes it available to
any ASTERIX sub-package that uses graphics. If another device
is already open, it will be closed first. The display surface
may optionally be divided into hard zones which are accessed
sequentially by plotting commands.
See the separate sections on Devices and XWindows.
