From QB64 Wiki
The END statement terminates a program without an immediate exit or ends a procedure or statement block.
- END [return_code%]
- END DECLARE
- In QB64 END can be followed by a code that can be read in another module using the _SHELL or _SHELLHIDE function.
- When END is used to end a program a pause and "Press any key to continue..." is displayed at the bottom of the 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 press or click on the window X box until the program is ready.
- When running a Qbasic BAS module from the command line, use SYSTEM to avoid returning to the IDE.
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 in QB or QB64.
