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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

This error may occur because a statement or command refers
to a file with a file number or name that is not specified
in the OPEN statement or is out of the range of file numbers
(valid range is 1-255) specified earlier in the program.
