Data Files

A data file is a text-based file that contains one or more program commands. A data file is processed by the program either through the program call command or by pressing the execute ( go ) button on the toolbar when the file is loaded in an i Editor pane. Data files may be nested (one file may use program call to run another). A modeling project, therefore, may be simple and consist of a single data file, or it may be limitlessly complex with many nested data files — or anything in between. The articulation of project structure, and control of its execution, is governed by the organization of its data files, and is up to the user to determine based on experience and personal preference.
