Command Reference

The EViews User’s Guide focuses primarily on interactive use of EViews using dialogs and other parts of the graphical user interface.

Alternatively, you may use EViews’ powerful command and batch processing language to perform almost every operation that can be accomplished using the menus. You can enter and edit commands in the command window, or you can create and store the commands in programs that document your research project for later execution.

This discussion documents the use of commands in EViews, along with examples of commands for commonly performed operations, and provides general information about the command, programming, and matrix languages:

The first section provides an overview of using commands in EViews:

• “Object and Command Basics” explains the basics of using commands to work with EViews objects, and provides examples of some commonly performed operations.

The next section discusses commands for working with specific EViews objects:

• “Working with Graphs” describes the use of commands to customize graph objects.

• “Working with Tables and Spreadsheets” documents the table object and describes the basics of working with tables in EViews.

• “Working with Spools” discusses commands for working with spools.

The EViews programming and matrix language are described in:

• “Strings and Dates” describes the syntax and functions available for manipulating text strings and dates.

• “EViews Programming” describes the basics of using programs for batch processing and documents the programming language.

• “External Connectivity” documents EViews features for interfacing with external applications through the OLEDB driver and various COM automation interfaces.

• “Matrix Language” describes the EViews matrix language.

The remaining sections contain reference material:

• “Command Reference” is the primary reference for commands to work with EViews objects, workfiles, databases, external interfaces, programs, as well as other auxiliary commands.

• “Operator and Function Reference” offers a categorical list of element operators, numerical functions and descriptive statistics functions that element operators, numerical functions and descriptive statistics functions that may be used with series and (in some cases) matrix objects.

• “Workfile Functions” describes special functions for obtaining information about observations in the workfile.

• “Special Expression Reference” describes special expressions that may be used in series assignment and generation, or as terms in estimation specifications.

• “String and Date Function Reference” documents the library of string and date functions for use with alphanumeric and date values.

• “Matrix Language Reference” describes the functions and commands used in the EViews matrix language.

• “Programming Language Reference” documents the functions and keywords used in the EViews programming language.

There is additional supplementary material:

• Appendix A. “Wildcards” describes the use of wildcards in different contexts in EViews.
