Syntax

X <'operating-environment-command'>;


Without Arguments

Using X without arguments places you in your operating environment, where you can issue commands that are specific to your environment.


Arguments

'operating-environment-command'

specifies an operating environment command that is enclosed in quotation marks.


Details

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:

  [cautionend]

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.


Comparisons

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.
