In general, SAS closes
the library data set at the conclusion of the SAS procedure or DATA
step that is processing the library. The TAPECLOSE option has no effect
on processing direct bound libraries or UFS libraries. Specifying
FREE=CLOSE on the JCL DD statement for a library is honored only if
TAPECLOSE has a value of REWIND, DISP, or FREE. If TAPECLOSE has a
value of REREAD or LEAVE, then the FREE=CLOSE specification is ignored.
For more information about FREE=CLOSE, see the IBM JCL Reference for
the version of
z/OS that your site is using.
Note: If the FILECLOSE data set
option is specified, then it overrides the TAPECLOSE system option.
