Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

END stops a BASIC program, procedure, or block.
 
END [{DEF | FUNCTION | IF | SELECT | SUB | TYPE}]
END [n%]
    ■ The value n% can be used by DOS or OS/2 batch files or by
      non-BASIC programs. Untrapped errors and fatal errors set the value
      of n% to -1.
 
Usage Notes
    ■ By itself, END stops program execution and closes all files. In a
      stand-alone program, END returns control to the operating system;
      in the QBX environment, END returns to the environment.
    ■ The following table shows where END is required:
