Peter, CP/M is dumb when it comes to keeping directory entries. It does not check to see if a file by that name already exists before allowing you to create a new one. You as the user are expected to check first to see if it exists, delete it if it does, then make the new file. Otherwise you will end up with two or more files by the same name. Also make sure that you do a proper close on any open files before exiting your program. Otherwise the directory will not be updated and any pending characters in the deblocking buffer will not be written to the file. --Keith
