{{PageDescription}}
|
|
* In '''QB64''', [[END]] can be followed by a code that can be read by another module using the [[SHELL (function)|_SHELL]] or [[_SHELLHIDE]] function (known as [https://blogs.msdn.microsoft.com/oldnewthing/20080926-00/?p=20743 '''errorlevel'''])
|
|
* When END is used to end a program, there is a pause and the message "Press any key to continue..." is displayed at the bottom of the program's window.
|
|
* If the program does not use END or [[SYSTEM]], the program will still end with a pause and display "Press any key to continue...".
|
|
* In '''QB64''', [[SYSTEM]] will end the program immediately and close the window.
|
|
* The '''QB64''' [[_EXIT (function)]] can block a user's Ctrl + Break key presses and clicks on the window's close button (X button) until the program is ready to close.

:''Explanation:''"Hello no one!" isn't returned because the program ended with the END statement no matter what is after that.
