# assign — Assign variable

ASSIGN assignes the value of a source variable to a target variable.

These three statements are semantically equivalent:

					<assign var="var[key]" var_source="var_source"/>
					<assign var="var.key" var_source="var_source"/>
					<assign var="var" key="key" var_source="var_source"/>

					These three statements are semantically equivalent:

					<assign var="var" var_source="var_source[key]"/>
					<assign var="var" var_source="var_source.key"/>
					<assign var="var" var_source="var_source" key_source="key"/>
