	I think it is the assembly language source *of* the forth, 
rather than source *for* the forth, in which case it would be in 
whatever format the assembler would expect.  But it could be in 
blocks (say, to assemble itself, or to cross-compile from the 
PC-based F83 to the Apple II).

	OK. Where would the directory tracks be in an Apple II disk 
image, and what would they mean?
