Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The Register window shows the current status of processor
     registers and flags.
 
     To open the Register window:
 
        ■ Choose the Register command from the View menu
       OR
        ■ Press F2
 
     CodeView highlights changed registers as you step through your
     program.
 
     If the 386 option is turned on, the Register window shows 32-bit
     registers. This option is available only in CV.EXE, the real-mode
     version of CodeView.
 
     To turn this option on:
 
        ■ Select the 386 Instructions command from the Options menu
       OR
        ■ Enter the O3+ command in the command window
 
     See: ◄Options Menu: 386 Instructions Command►
          ◄Options (O) Command-Window Command►
 
     CodeView allows you to change the value stored in any register.
 
        ■ To change a register value, overtype the register value,
          then move the cursor to a different line.
 
        ■ To change a flag value, double-click the value with the
          mouse.
 
        ■ To restore the original register value, press ESC (before
          you move the cursor) or choose the Undo command from the Edit
          menu (after you move the cursor).
 
     The Register window also displays the effective address at the
     bottom of the window. The effective address shows the actual
     location of an operand in physical memory. Use this window to
     debug in Assembly or Mixed mode.
