!!! Overview
[{$pagename}] or scalar is a storage location paired with an associated symbolic name (an [identifier]), which contains some known or unknown quantity of information referred to as a value.

The [{$pagename}] [NAME] is the usual way to reference the stored value; this separation of name and content allows the name to be used independently of the exact information it represents. The [identifier] in computer source code can be bound to a value during run time, and the value of the variable may thus change during the course of program execution.

[{$pagename}]s maybe Referenced [By-value] or [By-reference]
