You will notice that the version of LIBRARY is
not identified, because there is no LIBRARY
program loaded. If S4 sees what it thinks is a

ESC = NO
ENTER = YES.
If you do want to load a new library press ESC
then LIB . Put your LIBRARY ROM in the
socket and press ENTER S4 will load the
program contained in the LIBRARY ROM.
Then it will restart and run the program. If the
LIBRARY program loads correctly, S4 will

need to load the LIBRARY program. It will be
present in memory when you buy your S4 and
it will remain there, because S4's memory is
permanent and continuous for both programs
and data. The only reasons for loading a
LIBRARY are to upgrade to a new version or
