The filename is not saved anywhere, it's found in the command buffer when
the file is opened (the first step in the LOAD process).  If the file is not
found in the directory, nothing is saved, but if it is found, the DOS saves
the track and sector of the 1st block in the file (and it reads that sector).
The only way to find out what filename was sent by looking at DRIVE memory
is to have a program that is already in drive memory copy the command buffer
to a safe place.  You can't do this from the computer, because as soon as
you send a MEMORY-READ, you will have overwritten the filename.

Good luck.  Let me know if you succeed!
