Debugger command set?

[Matt Cole <mikaeline@inebraska.com>]

Okay, here's my story -- I just inherited an old Apple //e that was (strangely
enough), until the end of last semester, being used by one of the teachers
at my school to do grades on...this is, until his printer broke down. 
The school didn't want to try and find a printer that would hook up to
his computer (which seems to have a IEEE 1284B connector on it....same
as a PC printer), so they gave him a GS, with an ImageWriter....

Anyway, the story is that the school didn't want the //e any more, so I volunteered to take it off their hands, which they heartily agreed to.  Now, I'm re-learning BASIC, saving my programs on tapes, etc., and I'm finding that the //e seems to have an integrated assembler-level debugger, which can be accessed by typing "&" alone at the command prompt.  My question is, is there anyone that knows any commands for this debugger?  eg, how to modify data, assemble instructions, etc?

Any help would be appreciated.
