The subdocument mechanism for the statement __INC in model documents (the so-called Pre include mechanism) can be enabled with the ITP administration program. The directories where ITP has to search for the included documents can be specified in a search path.
The subdocument mechanism for the statement __INC in result documents (the so-called Post include mechanism) can be enabled with the ITP administration program. The directories where ITP has to search for the included documents can be specified in a search path. If no directories have been specified here, ITP will use the directories that have been specified at the search path for the pre-includes.
The ITPINCLUDELEVEL setting determines the maximum allowed number of nested include files. The level is set to 16 by default and can be changed with the ITP Administration Program.
