DRIVER for procedure GETKEYS(chr1,chr2)
Waits until a key is pressed, then returns ASCII char in chr1 and chr(0) in
chr2 for standard ASCII characters, or chr(27) in chr1 and a code character
in chr2 if an "escape sequence" character. See KEYCHART.DAT for translation.
NOTE that BACKSPACE and RETURN are not visible except by their activity--
they still function!
