**''$INCLUDE''** ''[[filename|]]''\\ **''$INC''** Includes a Timetable file with the file name ''''. This functions as if the entire contents of the file '''' appear at the place where the **''$INCLUDE''** line appears.  There is no maximum limit to how many files can be included into another Timetable, but the number of nested include statements cannot exceed ten.  That is to say, if you include a file, it can contain an **''$INCLUDE''** as well and so on up to a depth of ten levels. If you use relative path names, they will be evaluated from the path of the timetable file the **''$INCLUDE''** is in. If you build a complex include structure, check out the **''[[require|$REQ, $REQUIRE]]''** commands too - they can avoid including the same file more than once.
