Script Debugger saves the following information into a compiled script file:

• The compiled script bytecode.
• The script’s description, if any.
• Persistent information such as the current values of script properties.
• Script window state (such as its size and position) and view settings.
• The open or closed state of the result drawer — but this will be restored the next time you open the file only if you have checked the “Remember Result drawer state” General preference.
• Apple Event Log window tab view and mode settings.
• Libraries.
• Expressions.
• Breakpoints, if the script is saved in debug mode.
