===== MoodleScript: SET VARIABLE =====
===== MoodleScript Script Engine =====

=== Effect ===

Initialises a context key with a value or with the value of another variable.

=== Syntax ===

    SET VARIABLE <varname> FROM <litteral>

    SET VARIABLE <varname> FROM :<varname>

    SET VARIABLE <varname> FROM Litterals with :{<varname>} inside

=== Examples ===

    SET VARIABLE defautname FROM Default

    SET VARIABLE savedcourseid FROM :courseid

    SET VARIABLE extendeddefaultname FROM :{courseid}_with_extensions

===Attributs particuliers===

    * **varname**: The name of the variable to create, without spaces or special characters.
    * **litteral**: A literal string

=== Notes ===

The created variable is installed in the global context of the execution stack for the lifetime of the script, until it is overridden by another assignment.

When a variable is created from another variable, the latter must be defined in the global context of the script, otherwise an empty value will initialise the new variable.

A combined literal form can call existing context variables. Sub-variable calls are replaced by those found in the context at execution time.

=== Other defaults ===

None
