### Compiler Option Dependencies

Some options are required with other options:

- If you specify the listing file option /Le (expand macros), or one of /Li or /Lj (expand include files), you must also specify the /Ls option to include the source code.
- If you specify any of the listing options /Lp (set page length), /Lt (set title), or /Lu (set subtitle), you must also specify /L (produce listing file).
- Setting /O automatically sets /Oi, /Os and /Oq-.
