FILELOCK()

    FILELOCK() is used to lock files in multi-user systems.

    Syntax

    FILELOCK()

    Required Parameters

    None.

    Return Value

    A logical value: True (.T.) if the lock was successful, or False
    (.F.) if unsuccessful.

    If the lock is initially unsuccessful, the user will be given the
    option to wait for availability in the same fashion as with
    NET_USE().  Likewise, a dazzling screen will keep them amused while
    they wait, and the Charge theme will be played when the lock is
    finally successful.

    Sample Usage

    IF FILELOCK()
       DO reports
    ENDIF
