DLTF Routines

The display and lookup table file routines are used to create, access, and delete DLTF entries. These routines call upon label service routines to store and retrieve the required information, as well as remove specific entries from the DLTF. The routines will create a DLTF if one doesn't currently exist or add unique entries to an already existing file. The routines allow for the removal of specific entries within a DLTF but not for the DLTF as a whole. The only exception to this is when a deleted entry is the only entry within a DLTF. In this case the DLTF as a whole will be removed along with the entry. The complete removal of a DLTF can be easily accomplished at any time by use of the CMDEL application.

The overall design of these routines is to provide an interface between label service routines and DLTFs, thereby shielding applications from changes that may occur to either the label service or DLTF file formats.

An application program can access these routines by linking in the following object library:

     $LASLIB/world.a
