Library /sys$common/syshlp/sysmanhelp.hlb RESERVED_MEMORY, REMOVE, Qualifiers, /SYSGBL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Indicates that a reservation is for a system global memory
    resident section.

    You cannot combine this qualifier with the /GROUP or /NOGLOBAL_
    SECTION qualifier. This qualifier is the default unless you
    specify /GROUP or /NOGLOBAL_SECTION.
