Section 1.0 INTRODUCTION
This document describes the software created for the
display MicroVAX computer used on the Advanced Transport
Operating System (ATOPS) project at the Langley Research
Center. The software was developed by Computer Sciences
Corporation (CSC) for NASA under contract NASI-19038. This
document targets the software delivery of February 27, 1991
as a baseline system. Since a few items have been accepted
for the next delivery, they will also be included in this
document and noted as such.
The display MicroVAX computer is the host to the Sperry
microprocessor display system. The software residing in
that system is addressed by another document entitled:
Advanced Transport Operating System
COLORDISPLAY SOFTWARE
DOCUMENTATION
Microprocessor System
The display host computer works in tandem with another
MicroVAX computer, referred to as the Flight Management and
Flight Controls computer (FM/FC). The document
FLIGHT MANAGEMENT
/ FLIGHT CONTROLS
SOFTWARE DOCUMENTATION
should be referenced for information about FM/FC software.
Throughout this document, descriptions of software
modules are presented in a standardized format. The basic
template is shown on the next page. At the top of the form
is a header block containing miscellaneous information about
the module. Next appears a one or two sentence synopsis
used as a quick reference stating the purpose of the module.
A detailed description follows which may be a small para-
graph to several pages in length. Global symbol references
are listed next. These are the subroutines and common
variables referenced by the particular module. Note that
passed parameter variables are not shown here. Passed
parameters are provided in the CALLING SEQUENCE portion of
the header information block. When an asterisk is appended
to the name of a data variable listed in the gloabl
reference section it denotes a memory location modified by
the module.

Section 2.0 SYSTEM OVERVIEW
The various sub-sections of the system overview briefly
describe the overall configuration of the displays host soft-
ware on the MicroVAX flight computer. The reader should be
familiar with the VAX/VMS operating system. Several important
key words are listed below. Detailed information about these
concepts is provided by the VAX/VMS reference manuals. In
particular "Introduction to VMS" and "Guide to Using VMS" are
good places to start.
