to
enter a
jump
address.
If
a
jump
address
is
specified, system control will be transferred
to
this address after loading when
the file
is
later loaded
by
a L command. This feature
is
useful when

is
an
individual machine language program file.

is
not
specified.t

will retain
system control after file loading.

address
of
$6050,
enter
"6050"
from the keyboard as shown below.
