No, you have to specify the side number for every command before that as well. The first time you give a filename without "0:", there's a memory leak in the drive. But the leak is completely harmless until you try to use @.

Aha. So you're saying that always using "@0:" would actually work?

Frantic: The @-bug is real, but it's surrounded by many myths. Look it up. The actual bug happens when you run any drive command without explicitly specifying side 0. This causes one of the five drive buffers to become unavailable until the next drive reset. The @-command needs all five buffers, and if they are unavailable, the disk is silently corrupted. The data loss only becomes apparent much later. So again, the solution is to always specify the side number, but nobody does that. Instead you can power-cycle the drive before using the @-syntax.

I've got some notes somewhere in the source code for defMON, which always overwrites files when it saves (unless you explicitly save under a new name). The notes say that "@S:" should be used, rather than just "@:" or "@0:", to avoid some sort of bug. Maybe there is some sort of problem with this, but I've actually never heard anyone complain that it didn't work for them when they used defMON, so I guess that syntax actually does work.

Sorry to hear that, iLKke. Indeed, CBM-DOS doesn't overwrite files (unless you prefix the filename with @). When you try to save over an existing file, you actually get an error message displayed at the top of the directory pane, where it says "63, file exists,00,00" instead of the usual "00, ok,00,00".

Be careful: In some versions of the 1541 ROM, it is not safe to use the @-syntax. This is a famous bug. I would recommend saving under a new filename every time. But you can also use the erase command in Blackbird, to remove the old version of the file before saving.

Is the idea to manually erase the old file before saving a new one? I just lost hours of work because it wasn't overwriting the old file when I save :\

What Shadow said. That manual alone is a piece of art.

I can't compose so I really can't comment on the tracker itself, but I am really impressed by the fact that lft took the time not only to create the tracker, but also put together a 50+ page professional-looking documentation to a free C64 program!
