## Display Sizes

On VMS and unix systems, the screen size may be changed to either 80 or 132 columns by using the functions `w80` and `w132` respectively. Simply enter the appropriate function name at the `M-x` prompt in the minibuffer. The default binding for access to the minibuffer is ESC X. Most window systems, e.g., DECWindows, allow the window size to be changed. When this is done, jed should automatically adapt to the new size.

On the PC, at this time the screen size cannot be changed while jed is running. Instead it is necessary to exit jed first then set the display size and rerun jed.
