The Options (O) command allows you to view or set the state of the following CodeView options:
| Letter | Option | Display |
| A | Show Status Bar | If on, the status bar appears at the bottom of the screen. If off, the bottommost line becomes part of the window area. |
| B | Bytes Coded | If on, instruction addresses and machine code are displayed for assembly instructions. |
| C | Case Sense | If on, symbols are case-sensitive; if off, they are not. |
| F | Flip/Swap | If on, CodeView flips the program and output screens as the program executes. If off, no screen flipping is performed. |
| H | Horizontal Scroll Bar | If on, windows have a horizontal scroll bar. |
| L | Show Address | If on, addresses relative to BP for all local variables are displayed in the Local window. |
| N | Native Mode | If on, instructions are displayed in the native processor format. If off, p-code instructions are displayed. |
| S | Symbols | If on, symbols in assembly instructions appear in symbolic form. If off, they appear as addresses. |
| 3 | 386 | If on, registers appear in wide 80386 format, and you can assemble and execute instructions that reference 32-bit registers and memory. |
| V | Vertical Scroll Bar | If on, windows have a vertical scroll bar. |
The Local window always displays variables local to the current routine. You can specify a scope of additional variables to display in the Local window with OL form of the Options command. Using OL with no options displays the current scope setting for the Local window.
The O form of the command (all options) takes no arguments; it displays the state of all options. The other forms of the command (OF, OB, OC, OS, OL, O3, OA, ON, OH, and OV) can be used as follows:
With no arguments. The state of the option is displayed.
With the + or – argument. The + argument turns the option on; the – argument turns the option off.
As an alternative to typing the O command, you can view and set options on the Options menu.
Use the Options (O) command to set options when you first start CodeView. You can set these options in the following ways:
Give one or more O commands with the /C option on the CodeView command line or include a similar command line in the CodeView response file.
Give one or more O commands as the Autostart entry in the TOOLS.INI file.
In the following example, the O command is used to display current option settings. Then, the O3 and OF commands are used to display and set options for 386 mode and for screen flip/swap mode. Finally, the OL command turns on symbol addresses in the Local window and displays not only local variables but global variables as well.
