the includeFile of factor
includeFile ( expression )
Factor and expression yield strings.
The includeFile function returns a file that represents the include with the specified name. If no such include can be found, the includeFile function returns empty. In OpenXION, the locations searched for includes are determined by the includePaths property.
The includeFile function is specific to OpenXION; it is not part of the XION Scripting Language Standard.
To use this function, OpenXION's security settings must allow the FILE_SYSTEM_READ security key. If the required security key is denied, a script error will be triggered.
