| <p>Placeholders are useful for inserting the text of parts and answer boxes at specific points in the question. There are two types of placeholders:</p>
| |
| <ul>
| |
| <li>part's text placeholder (discussed below)</li>
| |
| <li>answer box placeholder (discussed on the next page)
| |
| </ul>
| |
| </div>
| |
|
| |
| The part's text placeholder allows inserting the text of a part at a particular point in the main question. The placeholder name is a string starting with <span style="font-family: monospace;font-size:113%;">#</span> and followed by a string of alphanumeric characters <span style="font-family: monospace;font-size:113%;">[A-Z a-z 0-9]</span>, such as <span style="font-family: monospace;font-size:113%;">#1</span>, <span style="font-family: monospace;font-size:113%;">#a</span>, <span style="font-family: monospace;font-size:113%;">#a1</span>, <span style="font-family: monospace;font-size:113%;">#1a</span>, <span style="font-family: monospace;font-size:113%;">#SubQuestion01</span>, etc. Note that, although the designation of the part's text placeholders is quite flexible, a simple designation such as <span style="font-family: monospace;font-size:113%;">#1</span>, <span style="font-family: monospace;font-size:113%;">#2</span>, <span style="font-family: monospace;font-size:113%;">#3</span>, etc. is often sufficient.
| |
|
| |
| At the point of insertion into the main question text, the placeholder name must be enclosed by curly braces <span style="font-family: monospace;font-size:113%;">{ }</span>. In the parts, the placeholder name is specified in the field called '''Placeholder name'''.
