The END statement terminates a program without an immediate exit or ends a procedure or statement block.
- In QB64, END can be followed by a code that can be read by another module using the _SHELL or _SHELLHIDE function (known as 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.
Example: In QB64 you won't return to the IDE unless you are using it to run or edit the program module.
Hello world! Press any key to continue...
- Explanation:"Hello no one!" isn't returned because the program ended with the END statement no matter what is after that.
- The message "Press any key to continue..." is displayed after the program ends, both in QBasic and in QB64.
