Deinstalls a page or swap file. Requires CMKRNL privilege.
    Any file installed with the SYSGEN command INSTALL can be
    deinstalled.

    If the specified file is being actively used by processes, this
    command simply marks the file as "deinstall pending". This
    prevents any new assignments or reservations to the file from
    occurring. When all outstanding references to the file have been
    removed, the deinstallation will complete.

    Files in the deinstall pending state are identified in the DCL
    command SHOW MEMORY/FILES display.
