Saving
in
the
Template
Suppose you misspelled TYPE
as
BYTE,
but
had not entered
the
command. (Set up
this
situation by typing
BYTE
and pressing
ffiJ
again.)
Your
screen displays:
BYTE
prog.asm_
To
avoid retyping
the
entire command, press
mJ.
The symbol @
appears
at
the
end of
the
line. This indicates
that
MS-DOS
has
put
the
new line
in
the
template, although
it
has
not sent
it
to
be executed.
Now
edit
the
line BYTE
prog.asm
so
it
becomes TYPE
prog.asm.
To
do
so, type:
ITl80ffiJ
The 8 copies a single character Y from
the
template to
the
command line. The
resulting
command line is:
,TYPE
prog.asm_
