| Any number of times I've found myself yearning for the old MS-DOS PC's
multiple video pages using EGA/VGA output cards. I have written, for
example, a whole series of very useful and complex real-time control
programs that use up to 8 simultaneous video pages for which the program has
to do nothing more to put something on a secondary page than to copy the
text & attributes to a different area of video memory than is used for the
primary page and the video memory for all pages exists simultaneously and
the program need do nothing to create them.
In *NIX systems I know how to write separate programs which receive input
either via a pipe or IPC messaging (or I guess shared memory too) but I was
wondering if there's something I've overlooked in getting a text-based
program in an xterm shell window to open a second window for (at least)
output?
TIA
