MS-DOS User's Reference
Note
that "previous" refers
to
an earlier string
of
text
specified in
an
S
or
R command.
If
you specify a question mark
(?)
in
the
R
command,
edlin
stops
at each line
with
text that
matches
textl,
displays
the
line
with
text2,
and
then
displays
the
prompt
"O.K.?". If you
press
Yor
RETURN, text2 replaces
textl,
and
edlin
looks for
the
next
occurrepce
of
textl.
It
continues
this
process
until
it
reaches
the
end
of
the
range
or
the
end
of
the
file. After
edlin
finds
the
last
textl,
it
displays
the
asterisk
prompt.
If
you
press any key
other
than
Yor
the
RETURN key after
the
"O.K?"
prompt,
textl
is left as is,
and
edlin
moves
to
the
next
occurrence
of
textl.
If
textl
occurs
more
than
once
in
a line,
edlin
individually replaces
each
occurrence
of
textl,
and
displays
the
"O.K?"
prompt
after
each
replacement. In this
way
you
can
replace
only
the
desired
textl
strings
and
prevent
unwanted
substitutions.
Examples:
Suppose
the
following file exists
and
is ready for editing:
1:
