<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>datarea</strong> utility reads or writes a data area.</p>
|
||
|
|
|
||
|
|
<p>In the first synopsis form, <strong>datarea</strong> reads the contents of the
|
||
|
|
<em>data-area</em> and writes it to standard output. By default, it reads the
|
||
|
|
entire data area.</p>
|
||
|
|
|
||
|
|
<p>In the second synopsis form, <strong>datarea</strong> writes to the
|
||
|
|
<em>data-area</em>. If <em>data</em> is specified, it is written
|
||
|
|
to the <em>data-area</em>. Otherwise, one line is read from standard input and written
|
||
|
|
to the <em>data-area</em>.</p>

<dd>For a character type data area, read or write the character positions specified by <em>substring</em>.
|
||
|
|
The <em>substring</em> is specified as a number range that consists of a number, a dash (-), and a
|
||
|
|
second number to select the character positions from the first number to the second number, inclusive.
|
||
|
|
If the first number is omitted, character positions from 1 to the second number are selected. If
|
||
|
|
the second number is omitted, character positions from the first number to the end of the data area
|
||
|
|
are selected.</dd>
