The method that you use to deallocate a file depends
on which method you used to allocate it:
-
If you used the FILENAME statement
or FILENAME function to allocate the file, include the CLEAR argument
to deallocate it:
filename books clear;
Note: The CLEAR argument is optional.
Specifying
FILENAME fileref; has
the same effect.
-
If you used the JCL DD statement
to allocate the file, then the file is automatically deallocated when
the job step ends. (There is no way to deallocate the file before
the job step ends.)
-
If you used the TSO ALLOCATE command
to allocate the file, then use the TSO FREE command:
free fi(books)
