Multiple window creation

Syntax: | `WINDOW\TILE nx ny nstart`
Defaults: | `nstart = 1`

The `WINDOW\TILE` command divides the graphics page up into `nx` horizontal by `ny` vertical windows, giving the first window the number `nstart`, which must be `> 0`. The total number of windows just defined will be `nx*ny`. The window numbered `nstart` will be in the upper left corner of the page, while the window numbered `nx*ny-nstart+1` will be in the lower right corner.
