Documentation Guide

For a short overview and guide to the SDT 3.02 user documentation, see chapter 3, Documentation Guide, in the volume SDT 3.02 Release and Documentation. This chapter contains the following:

Contents of the volumes making up the documentation
Reading Advice for the documentation
Typographic Conventions used in all volumes (see also the following pages).

Typographic Conventions

This section describes the typographic conventions used in all volumes of the SDT 3.02 user documentation.

Bold Style

If a word or phrase in a paragraph requires special attention, it is printed in bold style.

Italics

SDT terms and user interface objects, such as labels, menu names, menu items and button texts, are shown in italics. For example:

The Edit menu provides a Paste command...
Click on the OK button...
... stored in the work area.

Typewriter Font

File names, as well as some SDT-specific concepts, are shown in a typewriter font. For example:

The sdt.ssl file...
The textual output generated by the computer, as well as portions of source code and file contents, are also shown in that typewriter font. For example:

State1: 
  Sig1:INPUT
  Sig2:SAVED
State2: 
  Sig3:INPUT
  Sig1:UNHANDLED

When you are asked to type in characters from the keyboard during an interactive session, a bold typewriter font is used in order to distinguish user input from computer textual output:

Now, type in Convert, Demon, System

Command : List-Ready-Queue

Angle Brackets

Information within angle brackets "< >" denotes symbolic names which should be replaced by actual names. For example:

The syntax is "<process instance> <variable name>"...
Special keys or key combinations are shown in typewriter font within angle brackets:

To execute the command, press <Return>...
Hit <ctrl-c> to...

Cross References

References to chapters and volumes in the documentation are shown in italics. For example:

See chapter 3, Documentation Guide, in the volume SDT 3.02 Release and Documentation...
References to sections within chapters are quoted. For example:

See "Search List" on page 21...
References to figures / examples within the current chapter refer to the figure / example number. For example:

See Figure 4.

Run-in Paragraphs

Bulleted run-in paragraphs enumerates information where the order of appearance is not of significance. For instance:

The SDT Main Application (level 1 bullet)
- The Main Application's Exit button (level 2 bullet)

Steps denote enumerated information in which the order of appearance is of significance, or operations which you should perform in the specified order. For instance:

First...
Then...
Finally...

Special Effects

Illustrations and Figures

Throughout this manual, screenshots exemplify various situations which occur while using SDT. Although most of them are generated on a SUN workstation running the X Window System with the Motif window manager, they are valid for other computer and windowing systems as well, since the functional meaning remains unaffected. However, their appearance may slightly differ from the actual appearance on the screen when you are running SDT, depending on the window manager and the resource setup which was used when creating the illustrations.

Figure titles and comment text in a figure are shown in a sans-serif font:

Figure 999: The Figure Title.
