Introduction

You already own the best possible foundation for a technical

workstation—a vAx computer. The vaxstation 100 workstation terminal is a subsystem you can add to your vAX system as a low-cost,
practical alternative to a stand-alone workstation.
You can integrate a vaXstation 100 workstation into your current
VAX computing environment easily and economically. It comes
complete with display subsystem, fiber-optics link to your vax
UNIBUS, and layered workstation software for the vms operating sys-

tem. You don’t have to operate it in an air-conditioned computer
room; you can keep it in your office. It’s quiet, compact, and

unobtrusive.

The vaxstation 100- offers features of the most advanced workstations, like a high-resolution, 19-inch, monochrome monitor and the
ability to operate on multiple jobs through multiwindowing. The
human interface for the vaxstation 100 workstation is unequalled in
the industry, with unique capabilities that enhance productivity and
make the workstation easy to operate. With a vaxstation 100, you can
concentrate on the task, not the tool.

So now you have a choice: buy new systems and software and spend
- many hours developing your applications to acquire the benefits of a
technical workstation, or get the most out of what you already have
by adding a vaxstation 100 workstation subsystem.

This book will help you make that choice. It provides an overview of
the technical aspects of the vaxstation 100, including the many features that make this add-on workstation environment such an exciting productivity tool. But to really appreciate the vaxstation 100
workstation terminal, you have to try one. Call your local Digital
sales office and ask for a demonstration.

The vaxstation 100 is a package of hardware and software that
includes everything you need to add state-of-the-art workstation
capabilities to a UNIBUS VAX system. It’s not a stand-alone system; it’s

a subsystem. (You could, however, combine a vaxstation 100 workstation terminal with a vax-11/725 to form a stand-alone work-

19" P4 60 Hz

station system.)

The workstation can be attached to any uNIBUS vaX processor: a
VAX-11/725, vax-11/730, vax-11/750, vax-11/780, vax-11/782, or

VAX-11/785 system. This gives you an extraordinary range of computer power, from a small single-user system that can sit in your

office under your desk, to a large multiprocessing system supporting
a cluster of workstations..

Indeed, it’s the software that makes the vaxstation 100 workstation
such an extraordinary productivity tool. The rest of this book

describes the basic design of the software and the remarkable capabilities it gives you.

The vaxstation 100 workstation terminal is designed to help you use
your computer as efficiently and productively as possible. It does that

by letting you work on as many different tasks as necessary without

having to stop one task to begin another. In computer terms, it lets
you have all your jobs running at the same time. And any or all of
those jobs can be displayed on the screen through the use of multiple
windows.

Display Graphics Operations

Copy Area

Viewport

Physical Screen

Copy Area is a fundamental bitmap operation (sometimes referred
to as bitblt or raster-op). It moves a source image to a destination
image. The source and destination are rectangles of identical size.

Each source pixel replaces the destination pixel at corresponding
pixel points. The exact outcome of the Copy Area operation is determined by:
Source—The source is an image whose pixel values are used to update

the destination. The source can be a constant value that replaces all

pixels in the destination or it can be a program-controlled bitmap.

Source offset—The source offset specifies the point at which the upper

left corner of the source mask is placed.

Source mask—The source mask restricts the set of source pixels to be

used in the copy operation and defines the rectangular subset of the
source to be used to modify destination pixels. There are three types

of source masks: rectangle, virtual display, and bitmap.

Destination—The destination image can be a virtual display or a

bitmap. While the destination can be a bitmap, the bitmap must be
copied to a virtual display before the image is visible.

Destination offset—The destination offset determines the placement of
source pixels in the destination image. The source offset and source

mask define a set of source image pixels whose origin is relative to the
upper left corner of the source image. The destination offset specifies

where that origin should be placed in the destination image.

Map—The map defines the values used to replace the selected destination pixels.

’

Draw Curve

Draw Curve is similar to Copy Area. Both operations specify the
source with a source image, source offset, and source mask; both

specify the destination with a destination image and destination
offset. Draw Curve can also use a map to modify the way pixels
are replaced.

Draw Curve requires a path, a list of points (or segments) in the desti-

nation that defines the line or curve to be drawn. Each path segment
is described by the x and y coordinates of its end point and a flag
word. The flag word describes the characteristics of the segment
(such as curved or straight and draw or move). The starting point for
the first segment is the destination offset. The starting point in all
other cases is the end of the previous segment.
Draw Curve can use a pattern for drawing the line. A pattern string is

used to draw dashed or patterned lines and curves. A patterned line
alternates between writing and not writing pieces of a segment.
Print Text

Print Text writes a character string. The operation requires a font and”
a character string containing character codes. A font is a data structure containing bitmap images of the characters and the information

required to locate each image and to determine its width and height.
The Print Text operation scans the text string, copies each selected
character to its destination, and writes each one horizontally. To support string justification, the Print Text operation can add a fixed

number of pixels after each character or after each space character.
. Fonts can be used in two ways to specify character images: as a source

image and as a mask. When used as a source image, each character
containing both the character image and background is copied to the
destination. A map can be used to transform the pixel values for the
image and background. When used as a mask, the mask font defines
only the shape of the characters. The source image can be either a
constant or a halftone.

Fill Area

Fill Area uses a halftone source image to fill one or more closed

shapes, then copies the shapes to the specified location in the desti-

capabilities

The source image for Fill Area is either a constant or halftone. A path
specifies the closed area in the destination image. Fill Area causes one
or more areas of
a destination image to be filled with one or more
halftone shapes.
Flood Area

Flood Area is used when the boundary is not completely known, but

current state of the destination image and is determined by a flood

algorithm.
The flood algorithm determines the area of the destination to be
flooded. It locates the inside and outside portion of the closed area
-and selects those pixels inside the flooded area. The determination of
the bounded area requires a seed point and a boundary map.
The seed point specifies a single pixel in the destination image and
must be in the bounded area. The boundary map determines
whether points are interior points or boundary points. The algorithm examines the seed point and internal adjacent pixels, until all
have been examined. The inside area floods until it reaches the
boundary points.

VAXstation Libraries

vaxstation software includes two subroutine libraries: the vax-

station Display Management Library (vsTA) and the vaxstation CORE
Graphics Library (cer). They are indispensable tools for develop-

The vaxstation CORE Graphics Library is a general-purpose graphics

separates the description of an object to be drawn (such as a graph or

a diagram) from the physical details (for example, size and resolution). That way, you can use the application you develop for vaxstation on any other display supporting core with little or no

caL uses the following procedures:
Control procedures start and stop the graphics system, clear all or a portion ofa virtual display, and report errors.

Viewing transformation procedures describe the data manipulated by the
program and control how ccL displays it on a virtual display. For

example, scaling can reduce or enlarge the information within a win-

dow by modifying dimensions to cGL. The window doesn’t change,
only the information within the window.
Output primitive procedures draw the lines, curves, markers, and graph1CS text.

Attribute procedures control colors, styles, modes, and fonts.
Even though vsTA and cGL are two unique interfaces, providing two
ways of communicating graphics, an application program can use
both on the same virtual display.
Using the VAXstation 100 Workstation

The Utility Area

The Terminal Menu—If you select the border of an emulated terminal
display, you can position it on top of other jobs (Pop to top), store the

job in the utility area (Store job), move the terminal anywhere on the
screen (Move), remove the job from the screen (Logout job), access
the Terminal-settings document to change certain terminal charac-

teristics (Terminal settings), clear the terminal from the screen (Termi-

nal RESET), print a screen display if you have the printer option
(Print), or access the help document opened to a description of the
Terminal Menu (Help).

Document Menus—If you select the border of the notices, profile, or
help document, you can position the selected document on top of
other jobs (Pop to top), clear the document from the screen (Store),

move the document anywhere on the screen (Move), print a screen
display if you have a printer (Print), or access the help document

opened to the preface, notices, or profile section (Help).
Other Menus—In addition to these menus, programs can create their
own menus. Using this feature your application programs can
benefit from the same ease-of-use features as the vaxstation work-

station and integrate better with the workstation environment.

Similar to a stack of inboxes, the utility area provides convenient
receptacles for documents or jobs that don’t require your immediate
attention. It lets you keep your “desk” from getting too cluttered
with unnecessary displays, while making it easy to find and retrieve

them quickly. A few of the boxes are labeled and used by the vaxstation 100 software; the rest you can use to store jobs off-screen.

The vaxstation displays a representation of the utility area on the far
right-hand portion .of the screen in a vertical column the length of

the screen.

At the top of the utility area is displayed your name, the time, and the

date. Each of these is displayed in the format specified in your user
profile (the area where you can define and confirm the operating
characteristics for the vaxstation).
Beneath the date display is a series of boxes we refer to as the job
-storage area. Each compartment in the job storage area can contain

an icon that identifies a stored job. Storing a job removes it from the

screen, places it in the utility area (where it continues to process), and

displays a job icon. A stored job can be recalled for display by selecting its icon in the job-storage-area display.

The last three compartments are used to store workstation
documents. Specifically, they are the notices, help, and user profile
documents.

The notices document handles announcements and system messages
that arrive during a vaxstation session. Ifa message arrives while this
document is stored in the utility area, the notices icon is highlighted
and the vaxstation keyboard beeps.

references for related sections. This document provides very handy
reference material. By pressing the help key on the keyboard or
selecting the help item from any vaxstation menu, the help document opens to the relevant page.

Selecting the profile icon gives you access to the profile document to

review and modify your vaxstation characteristics. For example,

you can change the type of terminal the system creates at session
startup, your name, and the format for the time of day and date.

These changes are implemented immediately and remain in effect

from session to session until they are changed again.
Some Basic Operations

What follows are descriptions of some of the fundamental operations

ofthe workstation. They will illustrate how easy the vaxstation 100
workstation is to use.
Creating a Job

To create a job, you press the main-menu key on the keyboard. The
Main Menu appears on the screen. Using the mouse, you position

the pointer on the item you want (for example, Create Job DEC terminal or Create_Job TEK4014), press the mouse button, and the system

displays the appropriate terminal type already logged into your
account with an assigned job name. You are now ready to run your
application from this emulated terminal.
