Composed for my long ago aborted Commodore 64 game Tenebria - The Dark Age. Unsurprisingly the game developement stopped when the 1541 drive messed up the disk. I shouldn't have used the replace command on the disk drive, but it was so much easier than to scratch a file before writing a new one... I used it once, and the whole disk was unusable.
Never ever use SAVE"@:important file",8,1 if you want to have your cake, and eat it too.
