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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

■ If you encounter this error when running your program, a
  FILES, KILL, NAME, OPEN, PRINT, or RUN statement refers to
  a file that does not exist.
 
■ If you encounter this error when starting Visual Basic or
  when opening a file in Visual Basic, you may have a PWB
  .MAK file with the same base file name as your source file.
 
■ Possible solutions:
 
  • Correct any file references to files that do not exist.
 
  • Rename the PWB .MAK file.
 
  • Incorporate error checking into your procedure to prevent
    or trap this error.
