Adding Instructions
If
you have recorded a medium-sized program and have left
out
a crucial sequence
of
keystrokes right
in
the middle, you do not
have to
start
over.
The
missing sequence
of
keystrokes
can
be
recorded
in
the available steps following your program.
You
can then use the
miD
key to make an unconditional branch to the
sequence when
it
is
needed and then make a second uncondi-
tional branch back to the main part
of
your program
at
the end
of
the sequence.
