Library /sys$common/syshlp/dbg$help.hlb DEBUG, DELETE, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The DELETE command deletes either a global DEFINE symbol or a
    local DEFINE symbol. A global DEFINE symbol is defined with the
    DEFINE command without the /LOCAL qualifier. A local DEFINE
    symbol is defined in a debugger command procedure with the
    DEFINE/LOCAL command, so that its definition is confined to that
    command procedure.
