Issues an operating-environment command from within a SAS session
Valid: anywhere
Category: Operating Environment
See: X Statement in the documentation for your operating environment.
X < operating-environment-command >;
Using X without arguments places you in your operating environment, where you can issue commands that are specific to your environment.
operating-environment-command
specifies an operating environment command that is enclosed in quotation marks.
In all operating environments, you can use the X statement when you run SAS in windowing or interactive line mode. In some operating environments, you can use the X statement when you run SAS in batch or noninteractive mode.
Operating Environment Information: The X statement is dependent on your operating environment. See the SAS documentation for your operating environment to determine whether it is a valid statement on your system. Keep in mind:
The way you return from operating environment mode to the SAS session is dependent on your operating environment.
The commands that you use with the X statement are specific to your operating environment.
You can use the X statement with SAS macros to write a SAS program that can run in multiple operating environments. See SAS Macro Language: Reference for information.
In a windowing session, the X command works exactly like the X statement except that you issue the command from a command line. You submit the X statement from the Program Editor window.
The X statement is similar to the SYSTEM function, the X command, and the CALL SYSTEM routine. In most cases, the X statement, X command or %SYSEXEC macro statement are preferable because they require less overhead. However, the SYSTEM function can be executed conditionally. The X statement is a global statement and executes as a DATA step is being compiled.
