Reads the contents of the specified MDL file.




The name of a file containing MDL statements.
Data type: string




An *Include() statement can be used anywhere in an MDL file. There is no limit to the number of MDL files that can be included or to the level of nesting.

If no path is given in the file_name argument, MDL searches the directory of the parent file for the included file. If the file is not found, all directories specified in *Path() statements are searched for the included file.

The contents of the included file are read into the model when the model file is loaded.
