PB Halt will not invoke the issue of the close event of application

Found PB program Halt later did not call, application Close event, so Baidu a bit found

If you use only halt, the system aborts the application directly, and the object may not be released properly.
And halt close will normally close the main thread, so that the application close event will also execute normally, so halt should try not to use, recommended halt close
When PowerBuilder encounters Halt without the keyword CLOSE, it immediately terminates the application.
When PowerBuilder encounters Halt and the keyword close, it immediately executes the script for the close event for the A Pplication and then terminates the application. If There is no script for the Close event at the application level, PowerBuilder immediately terminates the application
