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out of date.
File with procedure already loaded
The file you attempted to load contains at least one
procedure definition, and there is already a file in
memory with a procedure of the same name.
Rename or delete the procedure definition in one of the
files, preferably the file in memory.
