You can redirect your SAS statements to come from an
external program rather than from a file by using the SYSINP= and
PGMPARM= system options. SYSINP= specifies the name of the program,
and PGMPARM= specifies a parameter that is passed to the program.
For more information, see
SYSINP= System Option: z/OS and PGMPARM= System Option: z/OS.
