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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Bad file name
A filename does not follow the appropriate naming
convention for BLOAD, BSAVE, KILL, or OPEN (for example,
the filename has too many characters).
