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, /OVER causes the debugger to
break at the specified points only within the routine in which
execution is currently suspended (not within called routines).
The /OVER qualifier is the opposite of /INTO (which is the
default).
