Control on Facility Level

The concept facility is here used for special features that may be used in one or several different modules. The control on facility level may take place in different ways:

1. Via a file in ASCII format that specifies a special customer's rules. The file is read into the application program at run time and may normally be checked for errors by the inithull module.

   Examples are:

   • Set-up of connection codes,

   • Definition of default cutouts,

   • The association between a user number of a cutout and the macro that creates it.

2. Via objects stored in the hull structure data bank. These objects in turn may be created and checked by inithull and they are in most cases described in a language based on the general Interpreter Language (TIL) syntax. The resulting objects have normally fixed and predefined names but they should sometimes be controlled by environment variables.

The detailed conditions can be found together with the documentation of each separate facility.
