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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Duplicate procedure names in file
The file you attempted to open contains two SUB or FUNCTION
procedures with the same name. Use an editor to rename
one of them, then open your file in QBasic.
