Meta-HTML Functions

A meta-HTML function has the following form:

%name(parameter, parameter...) 

The entire expression is replaced by a substituted value, where the parameters are used in determining the value to be substituted. The parameters are arbitrary sequences of characters separated by commas. Do not place quotes around the parameters unless they form part of the value to be used.

In the following example, the entire text is replaced by the contents of the message 126, 45 from the message catalog, or the phrase "Unable to load images" if that message isn't found.

%Message(126, 45, Unable to load images)
