whats that? does it work with any basic interpreter?
It's what it says in the readme...
"The DEV-Handler allows easy access to raw sectors of an exec type device under the dos.library environment."
It means you can access block devices, such as floppy drives, hard drives and partitions, as if they are files, straight from DOS.
Can your basic interpreter read files? If yes, then it can also read disks and partitions.
For example, you can load a raw image of a floppy disk into your basic interpreter simply by reading in the file DEV:DF0 (or if you prefer, DEV:trackdisk.device/0)
