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out of date.
Too many files
You have exceeded the number of file operations DOS allows
in a root directory. If your program is opening, closing,
and/or saving files in the root directory, change your
program so it uses a subdirectory.
