SOrry about that last posting; it turns out it didn't work if more than
one file included curses.h (as my second program did). Although it could
be fixed by making everything static, I felt that the 512 byte array
plus about 80 bytes for initscr/endwin routines, (about 600 total)
was just too much per file. So, I put the routines and array into
a second file. This is no longer transparent; you will need to add
bcurses.o to the makefile, or add bcurses.o to /usr/lib/libcurses.a
Once again, this is a nearly transparent way to buffer curses output
even in interactive programs.
: use /bin/sh
