Differences between Stored Compiled DATA Step
Programs and DATA Step Views
Stored compiled DATA step programs and DATA step views are similar in function.
They both store DATA step programs that can retrieve and process data stored in other
files. Both have the same restrictions and requirements (see “Restrictions and
Requirements for Stored Compiled DATA Step Programs” on page 680). For
information about DATA step views, see “DATA Step Views” on page 671.
Stored compiled DATA step programs and DATA step views differ in the following
• A stored compiled DATA step program is explicitly executed when it is specified by
the PGM= option in a DATA statement. The stored compiled DATA step is used
primarily in production jobs.
• A DATA step view is implicitly executed when the view is referenced as an input
data set by another DATA or procedure (PROC) step. Its main purpose is to provide
data one record at a time to the invoking procedure or DATA step.
• You can use the REDIRECT statement when you execute a stored compiled DATA
step. You cannot use this statement with DATA step views.
