The structure of the device independent Display Management Subsystem (DMS) and the interface routines that are available to the applications programmer for use in developing a set of portable image display utility programs are described.
The Transportable Applications Executive (TAE), an interactive multipurpose executive that provides commonly required functions for scientific analysis systems, is discussed. The concept of an executive is discussed and the various components of TAE are presented. These include on-line help information, the use of menus or commands to access analysis programs, and TAE command procedures.

NASA's Goddard Space Flight Center (GSFC) has developed a Transportable Applications Executive (TAE) for use in implementing portable applications software that can be shared by different research projects. Since many of the supported disciplines require the interactive display and manipulation of remotely sensed images, a device independent Display Management Subsystem (DMS) was written as a TAE extension. The DMS attempts to abstract and standardize the device dependent functions that are used in the display and manipulation of image data on image analysis terminals. This paper explores the concept of DMS and the interface routines that are available to the applications programmer for use in developing a set of portable image display utility programs.
