<ul>
<li>Part 1</li>
<li>Part 2</li>
<li>Part 3</li>
</ul>
</fieldset>
</td>
</tr>
</tbody>
</table>
The hierarchy operation breaks things into parts:<br>
The whole consisists of Part 1 and Part 2 and Part 3.
Sequência
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">
<tbody>
<tr>
<td style="vertical-align: top;">
<fieldset><legend>Warnier/Orr</legend>

<td style="vertical-align: top;">
<fieldset><legend>LDC</legend><b>Job</b>
<ol>
<li>Task A</li>
<li>Task B</li>
<li>Task C</li>
</ol>
</fieldset>
</td>
</tr>
</tbody>
</table>
Sequence orders things:<br>
The whole consisisis of first Task A, followed by Task B, then Task C.
Seleção
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">
<tbody>
<tr>
<td style="vertical-align: top;">
<fieldset><legend>Warnier/Orr</legend> <img

<td style="vertical-align: top;">
<fieldset><legend>LDC</legend><b>Color</b>
<br>
<dd>| Red</dd>
<dd>| Green</dd>
<dd>| Blue.</dd>

</tr>
</tbody>
</table>
Selection allows choices:<br>
Color consisists of either Red or Green or Blue.
Complemento
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">
<tbody>
<tr>
<td style="vertical-align: top;">
<fieldset><legend>Warnier/Orr</legend><img alt="Diagrama Sintático - Diagrama de Sintaxe Warnier/Orr Basics Complemento"

</td>
<td style="vertical-align: top;">
<fieldset><legend>LDC</legend><b>Action Code</b>
<dd>| Valid</dd>
<dd>| NOT Valid</dd></fieldset>
</td>
</tr>
</tbody>
</table>
Complement is the logical NOT:<br>
The Action Code is either Valid or NOT Valid.
Repetição
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">
<tbody>
<tr>
<td style="vertical-align: top;">
<fieldset><legend>Warnier/Orr</legend>
<img alt="Diagrama Sintático - Diagrama de Sintaxe Warnier/Orr Basics Repetição"

<li>Task A<br>
(3)</li>
<li>Task B<br>
(3,T)</li>
<li>Task C</li>
</ol></fieldset>
</td>
</tr>
</tbody>
</table>
Repetition provides looping:<br>
Job consists of first doing Task A 3 times, followed by 3 to T
repetitions of Task B then doing Task C 1 time.
Concorrência
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">

<fieldset><legend>LDC</legend><b>Job</b>
<ul>
<li>Task A</li>
<li>Task B</li>
</ul>
</fieldset>
</td>
</tr>
</tbody>
</table>
Concurrency allows things to happen at the same time:<br>
Job consists of Task A and Task B at the same time.
Bloco Begin/End
<table style="text-align: left;" border="0"
cellpadding="2" cellspacing="2">
