Cursor visibility:

The cursor foreground must be set to non-black (i.e. not background) in the workstation set-up on colour stations in order to ensure visibility inside the GKS window.

window size:

The size of the actual window is looked for in a descriptor file WINDOW.DAT under the current working directory or, if the file is not found, in the directory defined by the logical name GKS_WINDOW.

The format of the file is 4F5.3, A20 as follows:

1. window size X in metres
2. window size Y in metres
3. window position X on screen in metres
4. window position Y on screen in metres
5. window title

For example: 0.15 0.15 0.20 0.15 GKS_WINDOW_1. The first line in the file corresponds to workstation type 8601, the second to 8602 etc.

See also the utility routines GCCDWN and GCSDWN for information on how to set the window size and title from within an application program (on Page ).
