<p>Importing a new version from external source</p> <p><b>New page</b></p><div>The ExpressionScript supports the following syntax:<br /> *All standard mathematical operators (e.g. +,-,*,/,!);<br /> *All standard comparison operators (e.g. &lt;,&lt;=,==,!=,&gt;,&gt;=, plus their equivalents: lt, le, eq, ne, gt, ge);<br /> *Parentheses (so you can group sub-expressions);<br /> *Conditional operators (e.g. &amp;&amp;,| | and their equivalents: and, or);<br /> *Single and double-quoted strings (which can each embed strings with the other quote type);<br /> *Comma operator (so can have a list of expressions and just return the final result);<br /> *Assignment operator (=);<br /> *Pre-defined variables (to refer to questions, question attributes, and responses) - e.g., the [[SGQA identifier|SGQA codes]];<br /> *Pre-defined functions (there are already 80+, and it is easy to add more).</div>
