Effects of errors on scripts
Most errors will not abort a running script. The only time a script is aborted is when a Lua run-time
(event code -286, "TSP runtime error") is detected. Run-time events are caused by actions such as
trying to index into a variable that is not a table.
Syntax errors (event code -285, "Program syntax") in a script or command will prevent execution of
the script or command.
