     If you run CodeView on an 80386 or 80486 machine, you can take
     advantage of the following 80386/486 features:
 
        ■ 80386 debug registers. These registers allow CodeView to
          implement certain types of breakpoints through the processor
          itself, thus increasing the speed of program execution.
 
          To use debug registers, give the ◄/R option► on the
          ◄CV or CVW command line►.
 
        ■ 32-bit registers and instructions. You can display the
          CodeView ◄Register window► in the wider 80386 format, and
          you can assemble and execute 80386/486 instructions that
          reference 32-bit registers and memory.
 
          To use 80386 registers, and 80386 or 80486 instructions,
          choose the ◄386 Instructions► command from the Options menu
          or enter the ◄O3► command in the ◄command window►.
