If
both
the
Iw
and
Ic
options
are
specified,
then
Fe
compresses
white
space and ignores case. For example,
if
an
underscore
represents a
white
space,
then
the
following
two
lines match:
The
IL
switch compares
the
files in ASCII mode. This switch is
the
default
when
you
compare
files that
do
not
have
extensions
of
.exe, .com, .
.rys,
.ob}, . lib,
or
.bin.
The ILb switch sets the internal line buffer
to
n lines. The default
length
of
the
internal buffer is 100 lines. Files
that
have
more
than this
number
of
consecutive, differing lines will
abort
the
comparison.
The
In
switch displays
the
line
numbers
on
an ASCII comparison.
The
It
switch does
not
expand
tabs
to
spaces.
The
default is
to
treat tabs as spaces
to
8-column positions.
The
Iw
switch causes
Fe
to
compress
white
space
(tabs
and
spaces)
during
the
comparison. If a line contains several spaces
or
tabs
in
a row, these characters
are
considered
a single
white
space.
Note that although
Fe
compresses
white
space, it
does
not
ignore
it.
The
exception
is beginning
or
ending
white
space
in a line,
which
is ignored. For example,
of
the
next
four examples,
the
first
three
match,
but
the
fourth
does
not
(note
that
an
underscore
represents a
white
space):
More
data
to
be
found

______
_
The Innnn switch specifies
the
number
of
lines
that
must
match
after
Fe
finds a difference
between
files.
If
the
number
of
match- L
ing lines in
the
files is less than this number,
Fe
displays these .
matching lines as differences.
