Open a device

PCOPEN  (PTOPEN) reads the MIDAS graphics keywords and initialises the device using this keyword setup. The device limits are set according to the currently assigned device (with the command ASSIGN/GRAPHIC). The keyword setup determines: If the access mode is ``new plot'' PCOPEN (PTOPEN) opens a new plot file or overwrites an existing one with the same name. If the access mode is ``over plot'' PCOPEN (PTOPEN) appends to an existing plot file.
