The ESC 247 code allows the programmer
to
switch the various shift keys
on
and
off. Thus the numeric key
pad
can be set
on,
or
the shift key 'held
down'.
The key state
is
set
to
normal by the user pressing the appropriate key, so it
is
advisable
to
program with the possiblity in mind
that
the key may be reset
outside program control.
The sequence
