Customizing Your SAS Session

Setting Default System Option Settings

You can use a configuration file to store system options with the settings that you want. When you invoke SAS, these settings are in effect. SAS system options determine how SAS initializes its interfaces with your computer hardware and the operating environment, how it reads and writes data, how output appears, and other global functions.

By placing SAS system options in a configuration file, you can avoid having to specify the options every time that you invoke SAS. For example, you can specify the NODATE system option in your configuration file to prevent the date from appearing at the top of each page of your output.

Operating Environment Information: See the SAS documentation for your operating environment for more information about the configuration file. In some operating environments, you can use both a system-wide and a user -specific configuration file.

Executing Statements Automatically

To execute SAS statements automatically each time you invoke SAS, store them in an autoexec file . SAS executes the statements automatically after the system is initialized . You can activate this file by specifying the AUTOEXEC= system option.

Any SAS statement can be included in an autoexec file. For example, you can set report titles, footnotes, or create macros or macro variables automatically with an autoexec file.

Operating Environment Information: See the SAS documentation for your operating environment for information on how autoexec files should be set up so that they can be located by SAS.

Customizing the SAS Windowing Environment

You can customize many aspects of the SAS windowing environment and store your settings for use in future sessions. With the SAS windowing environment, you can

  • change the appearance and sorting order of items in the Explorer window

  • customize the Explorer window by registering member, entry, and file types

  • set up favorite folders

  • customize the toolbar

  • set fonts, colors, and preferences.

See the SAS online Help for more information and for additional ways to customize your SAS windowing environment.



Conceptual Information about Base SAS Software

SAS System Concepts

SAS system-wide concepts include the building blocks of SAS language: rules for words and names , variables , missing values, expressions, dates, times, and intervals, and each of the six SAS language elements - data set options, formats, functions, informats, statements, and system options.

SAS system-wide concepts also include introductory information that helps you begin to use SAS, including information about the SAS log, SAS output, error processing, WHERE processing, and debugging. Information about SAS processing prepares you to write SAS programs. Information on how to optimize system performance as well as how to monitor performance.

DATA Step Concepts

Understanding essential DATA step concepts can help you construct DATA step programs effectively. These concepts include how SAS processes the DATA step, how to read raw data to create a SAS data set, and how to write a report with a DATA step.

More advanced concepts include how to combine and modify information once you have created a SAS data set, how to perform BY- group processing of your data, how to use array processing for more efficient programming, and how to create stored compiled DATA step programs.

SAS Files Concepts

SAS file concepts include advanced topics that are helpful for advanced applications, though not strictly necessary for writing simple SAS programs. These topics include the elements that comprise the physical file structure that SAS uses, including data libraries, data files, data views, catalogs, file protection, engines, and external files.

Advanced topics for data files include the audit trail, generation data sets, integrity constraints, indexes, and file compression. In addition, these topics include compatibility issues with earlier releases and how to process files across operating environments.
