window size:

The size of the actual window is looked for in a descriptor file gks_characteristic (for GPR) and gks_workstations.config (for GSR). Private versions of these files may be installed in the user's naming directory, otherwise default versions are taken.

The format of gks_characteristic is 5I5 and that of gks_workstations.config is 7I5. For gks_characteristic the first two numbers are the position in raster units of the top left-hand corner of the window, and the second two numbers are the width and height. The file contains six lines corresponding to the workstation types 10001...10006. For gks_workstations.config the first number is the workstation type, and the next four numbers are the same as above. The seventh number is a switch (0/1) to control whether or not the graphics windows have a border.
