end -- stop loading a file

Usage:

end
Consequences:
- This symbol, encountered at top level, causes loading of the current input file to be stopped.
- Alternatively, in the debugger it causes the current code to be abandoned, and the debugger to be re-entered one level further up. If there are no more suspended levels of execution, then control is returned to the top level.
