System Options under z/OS

SYSPREF= System Option: z/OS

Specifies a prefix for partially qualified physical filenames.
Default: user profile prefix for interactive, user ID for batch
Valid in: configuration file, SAS invocation, OPTIONS statement, OPTIONS window
Category: File Control: EXTFILES
z/OS specifics: all





The SYSPREF= option specifies a prefix to be used in constructing a fully qualified physical filename from a partially qualified name. Wherever a physical name must be entered in quotation marks in SAS statements or in SAS windowing environment commands, you can enter a data set name in the form '.rest-of-name', and SAS inserts the value of the SYSPREF= option in front of the first period.

Unlike the user profile prefix, the SYSPREF= option can have more than one qualifier in its name. If, for example, SYSPREF=SAS.TEST, then '.SASDATA' is interpreted as 'SAS.TEST.SASDATA'. The maximum length of prefix is 42 characters.

If no value is specified for SYSPREF=, then SAS uses the user profile prefix (in the interactive environment) or the user ID (in batch).
