     You can set breakpoints to break execution when any of the
     following conditions are true:
 
       1. The program reaches a given source line, function, label,
          or address.
          See: BP Command (location)
               Set Breakpoint Command (location)
 
       2. An expression becomes true (nonzero). The CodeView
          expression evaluator evaluates this type of expression based
          on the the currently visible function.
          See: BP Command (expression=true)
               Set Breakpoint Command (expression=true)
 
       3. The value of an expression or memory range changes.
          CodeView references this type of expression by memory
          location. As a result, the original value of the expression
          is checked no matter which function is currently visible.
          See: BP Command (expression changes)
               Set Breakpoint Command (expression changes)
 
       4. Conditions 1 and 2.
          See: BP Command (location/expression=true)
               Set Breakpoint Command (location/expression=true)
 
       5. Conditions 1 and 3.
          See: BP Command (location/expression changes)
               Set Breakpoint Command (location/expression changes)
