Functions and CALL Routines |
Submits an operating environment command for execution.
-
command
-
specifies any of the following: a system
command that is enclosed in quotation marks (character string), an expression
whose value is a system command, or the name of a character variable whose
value is a system command that is
executed.
Operating Environment Information: See
the SAS documentation for your operating environment for information about
what you can specify.
Restriction: |
The length of the
command cannot be greater than 1024 characters, including trailing blanks. |
The behavior of the CALL SYSTEM routine
is similar to that of the X command, the X statement, and the SYSTEM function.
It is useful in certain situations because it can be conditionally executed,
it accepts an expression as an argument, and it is executed at run time.
