Reserved Words

There are very few reserved words in the Railo CFML templating language, but there are a few that cannot be used all over the place.

Those words are:

• null (since Railo 4.1)
• true
• false

Even words such as "application" and "function" can be used as they are not reserved, so code such as:

<cfscript>
	application = 1;
	function = 1;
</cfscript>	

is still valid, but since the words above are NOT valid, the following is NOT allowed :

<cfscript>
	true = 1;
	null = 1;
</cfscript>

In Railo Server scope names are always invoked first, which therefore basically makes all scope names, e.g. variables, url, form, session, etc... reserved words.
