A /phanumeric Editing
An
110
item
matched
with
an
'A'
or
'Aw'
descriptor
must
have type
character
or
be
defined with Hollerith
data.
If
the field width
'w'
is
specified, the field consists
of
'w'
characters. Otherwise, the
number
of
characters
in
the
field
is
the length
of
the
110
list item.
On
input,
if
the
character
string
is
longer
than
the specified width, the string
is
trun-
cated
on
the right.
If
the specified width exceeds the length
of
the
character
string,
the string
is
blank-filled
on
the right.
The
same
is
true
on
output,
except
that
blank
filling
is
done
on
the left.

k
is
an

Apostrophe
Editing
The
apostrophe
edit descriptor
can
be used only for
output.
It
causes the
characters
enclosed in
apostrophes
to
be written
out
literally.
To
indicate
an
apostrophe
within
the
character
field, show it as two consecutive
apostrophes.
