SAS Companion for the OS/2 Environment

Glossary

action bar	See menu bar.
active window	a window that is open, is displayed, and contains the cursor. Only one window can be active at a time.
ASCII	an acronym for the American Standard Code for Information Interchange. ASCII is a 7-bit character coding scheme (8 bits when a parity check bit is included) including graphic (printable) and control (nonprintable) codes.
ASCII collating sequence	an ordering of characters that follows the order of the characters in the American Standard for Information Interchange (ASCII) character coding scheme. The SAS System uses the same collating sequence as its host operating system.
AUTOEXEC.SAS	a file containing SAS statements that are executed automatically when the SAS System is invoked. The autoexec file can be used to specify some SAS system options, as well as librefs and filerefs that are commonly used.
batch file	a file containing OS/2 commands organized for sequential processing. Batch files usually are identified with a .BAT or .CMD extension.
batch mode	a method of executing SAS programs in which a file containing SAS statements and any necessary operating system commands is submitted for batch processing. While the program executes, control returns to the terminal or workstation environment where you can perform other tasks. Batch mode is sometimes referred to as running in the background. The job output can be written to files or printed on an output device. Under OS/2, a Status window associated with the SAS job reports what SAS job is running and where the log and procedure output files are written.
buffer	a memory area reserved for use in performing input/output (I/O) operations.
catalog	See SAS catalog.
catalog entry	See entry type.
child window	a window that is invoked from or contained in another window (the parent window). For example, each SAS window, such as the EXPLORER, PROGRAM EDITOR and LOG window, is a child window of the main SAS window.
client	(1) in a network, a workstation requesting services from the server. See also server. (2) in pipes, unnamed pipes, and DDE, an application that sends data to or receives data from an application acting as a server. See also server.
Clipboard	a temporary storage place managed by OS/2 for data information that is being passed from one application to another. For example, you can use the Clipboard to pass information between Excel and your SAS session.
command prompt	the symbol after which you enter operating system commands. Under OS/2, the default command prompt is C:\>.
CONFIG.SYS	a system file that contains OS/2 configuration commands that specify the properties of the operating system, including device drivers, file-handling elements, and memory-management options.
configuration file	in the SAS System, an external file containing SAS system options, often called SASV8.CFG. The options in the file take effect when you invoke the SAS System. See also SASV8.CFG.
Control menu	under OS/2, the pull-down menu in the top left corner of most windows (including SAS windowing environment windows) that enables you to move and size windows. You can also use the Control menu to close a program and to select the Task List.

Another name for directory is "folder".
DLL	See dynamic link library (DLL).
docking view	a view of the main SAS window where a dockable window, such as the Explorer or Results windows, is docked to the left side of the main SAS window. A dockable window typically contains a listing of folders or files. When an item in a docked window is opened, the contents of the item is displayed in a separate window to the right of the docked window. The docking view allows for easy navigation within the SAS System.
download	to copy a file from the remote host to the local host.
drag	to press and hold a mouse button while moving the mouse.
dummy variable	(1) a variable used as a placeholder. Dummy variables usually do not have meaningful values. (2) in some statistical applications, a numeric variable whose value is limited to 1 or 0.

SAS data view	a SAS data set in which the descriptor information and the observations are obtained from other files. SAS data views store only the information required to retrieve data values or descriptor information.
SAS windowing environment	an interactive, windowing interface to SAS System software. Commands can be issued by typing them on the command line, pressing function keys, or selecting items from menus or menu bars. Within one session, many different tasks can be accomplished, including preparing and submitting programs, viewing and printing results, and debugging and resubmitting programs.

Toolbox	under OS/2, a feature of the SAS System that enables you to associate an icon with any SAS System command or macro. Selecting the icon executes its associated command or string of commands. The Toolbox is a dialog box and can be moved. See also toolbar.
unnamed pipe	also called an anonymous pipe (or simply pipe), this type of pipe is always one way. It is typically used to communicate between a parent process and a child process. Within SAS, the SAS System is the parent process that invokes (and reads data from) a child process.
Unrecoverable Application Error (UAE)	the OS/2 error message that appears when an application violates system integrity. The error can be caused by any application that is running or by the operating system.
upload	to copy a file from the local host to the remote host.
USER data library	a SAS data library defined with the libref USER. When the libref USER is defined, the SAS System uses it as the default libref for one-level names.
view engine	an engine that enables the SAS System to process SAS data views. A view engine performs in a transparent manner. See also SAS data view.
Window List	under OS/2, the list of active tasks. You can access the list by simultaneously pressing the left and right mouse button in the OS/2 Workplace Shell. You can use this list to switch from one task to another, stop a task, and so on.
WORK data library	the SAS data library automatically defined by the SAS System at the beginning of each SAS session or SAS job. It contains SAS files that are temporary by default. When the libref USER is not defined, the SAS System uses WORK as the default library for SAS files created with one-level names.
