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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

:nAdd Watch Command
Use to continuously watch the value of a variable or the
condition (-1 for true or 0 for false) of an expression
as your program executes.
 
Watched variables appear in the Watch window at the top
of the screen.
 
Note: The message 'Not watchable' appears in the Watch
      window if QuickBASIC cannot access the value of the
      variable.
