(Default) Applies only to breakpoints set with the following
    qualifiers (that is, when an address expression is not explicitly
    specified):

       /BRANCH
       /CALL
       /INSTRUCTION
       /LINE

    When used with those qualifiers, /INTO causes the debugger to
    break at the specified points within called routines (as well as
    within the routine in which execution is currently suspended).
    The /INTO qualifier is the default and is the opposite of /OVER.

    When using /INTO, you can further qualify the break action with
    /[NO]JSB, /[NO]SHARE, and /[NO]SYSTEM.
