About the statusdict

Most system parameters are accessed through a special dictionary

named statusdict. The name statusdict is a vestige of an early

design. The statusdict is the repository for machine- and

configuration-dependent operators and values. These operators and

values defined in the statusdict vary from one implementation of

PostScript to another. The operators and values described herein

may not apply to other PostScript printers.

You must enter this dictionary in order to change system

parameters. Although PostScript contains other data structures

(known as dictionaries), such as the serverdict, the statusdict is the

dictionary this chapter documents.

Additional PostScript information can be found in three books, The

PostScript Language Reference Manual, The PostScript Language

and Graphic Design and The PostScript Language Tutorial and

Cookbook, published by Addison-Wesley.

Entering the statusdict

There are two ways to enter the statusdict:

1. Send a file to the printer with the following command at the

top:

statusdict begin

2. Use the interactive mode and the command:

statusdict begin

Either of these procedures gets you into the statusdict. You can then

change system parameters by invoking operators by their names

and specifying new parameters.
