   |________________________________________________________________________|

file-name-1
Designates the file upon which the CLOSE statement is to operate. If more than one file-name is specified, the files need not have the same organization or access. File-name-1 must not be a sort or merge file.

REEL/UNIT
Under OS/390 and VM, you can specify these phrases only for QSAM multivolume or single volume files. The terms REEL and UNIT are interchangeable.

Under AIX, OS/2, and Windows, REEL and UNIT are treated as comments.

WITH NO REWIND and FOR REMOVAL
Under OS/390 and VM, these phrases apply only to QSAM tape files. If they are specified for storage devices to which they do not apply, they are ignored.

Under AIX, OS/2, and Windows, WITH NO REWIND and FOR REMOVAL are treated as comments.

A CLOSE statement can be executed only for a file in an open mode. After successful execution of a CLOSE statement (without the REEL/UNIT phrase if using format 1):

If the FILE STATUS clause is specified in the FILE-CONTROL entry, the associated status key is updated when the CLOSE statement is executed.

If the file is in an open status and the execution of a CLOSE statement is unsuccessful, the EXCEPTION/ERROR procedure (if specified) for this file is executed.
