The FUNCTION tag is used to create functions. These functions must exist in one of two places. They can either exist in the server "Functions.aro" file, or within the curent executing script.

Functions have access to all of the currently defined variables and may also receive variables passed with the use of the PARAM tag.

To call a function, the IMPORT tag is used.
