While using the 'after quit' command successfully in my current use case.
There are some small issues and a feature request i want to report.

• after quit is not documented in 'help after'
• name is strange as osd menu + cmd are called 'exit'.
• quit/exit are both strange language as it describes something
  different then what is happening.
  Some ~examples; 'after exit_request' or preexi

If you look at the pink dress, you see the color in the screenshot is a lot brighter?

Documentation must explicitly state that code in DEV_BASSTAT must not change HL register, If HL is changed then the _SYSTEM gives Syntax error if HL happens not to point to byte with value of 0.
