/SHARE (default)
       /NOSHARE

    Qualifies /INTO. Use with /INTO and one of the following
    qualifiers:

       /BRANCH
       /CALL
       /INSTRUCTION
       /LINE

    The /SHARE qualifier permits the debugger to set tracepoints
    within shareable image routines as well as other routines. The
    /NOSHARE qualifier specifies that tracepoints not be set within
    shareable images.
