LOAD"*",8,1 will load the last program loaded. If there was none,
it will then load the first program on the disk.

The ",1" is what is called the relocate flag. When it is notr there (or ",0")
it tells the 64(or any commodore) to load the program at wherever the
BASIC memory space starts. A ",1" tells it to load the program into whatever
area of memory from which it was saved. (Usually used for machine language)
This is why you get a screwed up screen if you use LOAD"$",8,1 to get a
directory.

To change a devce number on the 1541 (1571, 1581 too) use:

OPEN 15,"dn",15
PRINT#15,"M-W"CHR$(119)CHR$(0)CHR$(2)CHR$("New Device Number" + 32)CHR$("New
Device Number" +64)
CLOSE 15

"dn" is the current device number of your drive (probably 8)
and "New Device Number" is the number you want to change it to.
(Anything from 9-127 or so I think)
