To
insert a space
between
the
word
type and
the
filename
invest rpt, you pressed INS and then
the
SPACEBAR. Finally,
to
copy
the
rest
of
the
template to
the
command line, you pressed F3 and
then
the RETURN key.
The
command line type investrpt has
been
processed by MS-DOS,
and
the
template now looks like this:
type
invest.rpt.
If you had misspelled type as pyte, for example, a
command
error
would
have occurred. Still, instead
of
throwing away
the
whole
command, you
could
save
the
misspelled line before pressing
the
RETURN key. You can
do
this by pressing
the
FS
key before
the
RETURN key, creating a
new
template:
pyte
invest.rpt
You can then
edit
this
error
by pressing
the
following
two
keys:
FI
and f3. The FI key copies a single character from
the
template
to
the
command line, resulting in
the
command
that you want:
type
invest.rpt
As
an alternative, you can use
the
template that contains:
pyte
invest.rpt
Then
you can use
the
DEL and INS keys to
get
the
same result,
as follows:
DEL DEL
FI
INS yp F3
