Setting the Scrolling Region on VT100's VT220's VT320's VT420's, VT510's etc.

All the feedback is greatly appreciated. THANK YOU!!!!!!!!!!!! The simple solution seems to be to change: <ESC>[8;24r to <ESC>[8r since that defaults to the bottom of the screen. The 3 characters which are removed need to be replaced if SIPP is used to simply patch the file under RT-11 or to patch the file used by any other operating system for that matter. If required, placing 3 zeros, "0", in front of the "8" to form: <ESC>[0008r is probably the most straight forward solution. As far as I know, all current and hopefully all future real DEC VT100 terminals an emulations of the DEC VT100 terminals will probably implement the missing second parameter for the bottom line of the scrolling regions as the bottom line of the screen.
