banner.icn: Program to display banner

   Here is a a handy little code fragment called banner. I
know icon is mostly in the unix world and unix already has a banner
command. But I'm mostly in the DOS and VMS world so I offer this little
banner code. It outputs enlarged letters (5x6 matrix) portraite. With a
little diddling you can change the scale or font since this is the source.
Maybe it can be made to take an input file as a font, and maybe even from
xwindows. But this is a simple one. I include a main() procedure that
calls it so you can test it and build from there. Enjoy!
