|See:||OPTIONS Statement under z/OS|
The change that is made by the OPTIONS statement remains in effect for the rest of the job, session, SAS process, or until you issue another OPTIONS statement to change the options again. You can specify SAS system options through the OPTIONS statement, through the OPTIONS window, at SAS invocation, and at the initiation of a SAS process.
Note: If you want a particular group of options to be in effect for all your SAS jobs or sessions, store an OPTIONS statement in an autoexec file or list the system options in a configuration file or custom_option_set.
Note: For a system option with a null value, the GETOPTION function returns a value of ' ' (single quotation marks with a blank space between them), for example EMAILID=' '. This GETOPTION value can then be used in the OPTIONS statement.
Operating Environment Information: The system options that are available depend on your operating environment. Also, the syntax that is used to specify a system option in the OPTIONS statement might be different from the syntax that is used at SAS invocation. For details, see the SAS documentation for your operating environment.
The OPTIONS statement requires you to enter the complete statement including system option name and value, if necessary. The SAS OPTIONS window displays the options' names and settings in columns. To change a setting, type over the value that is displayed and press ENTER or RETURN.
