VMS Help SET, CPU, Qualifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

1 - /ALL

    Applies the specified operation to all CPUs in the active set.

2 - /CAPABILITY

       /CAPABILITY
       /NOCAPABILITY

    Allows bits in the process user capability mask to be set or
    cleared individually, in groups, or all at once.

                                   NOTE

       The SET CPU/[NO]CAPABILITY command will fail if there is
       an active process that requires a capability that is not
       available on any remaining active CPU.

    Specifying the /CAPABILITY qualifier has no direct effect, but
    merely indicates the target of the operations specified by the
    following secondary qualifiers:

    /SET=(n[,..Sets all user capabilities defined by the position
               values n, where n has the range of 1 to 16.
    /CLEAR=(n[,Clears all user capabilities defined by the position
               values n, where n has the range of 1 to 16.

    The secondary qualifiers can all be used at once as long as the
    user capability bits defined in the /SET and /CLEAR parameters do
    not overlap.

    The /NOCAPABILITY qualifier clears all user capability bits.

3 - /CLEAR

       /CLEAR=(n[,...])

    Clears all user capabilities defined by the position values n
    specified by the /CAPABILITY qualifier.

4 - /GLOBAL

    Modifies the global cell SCH$GL_DEFAULT_CPU_CAP. This global cell
    is used to initialize the user capability mask of CPUs that are
    brought into the active set for the first time.

5 - /SET

       /SET=(n[,...])

    Sets all user capabilities defined by the position values n
    specified by the /CAPABILITY qualifier.
