Thanks, this gives me enough information.

I now know why so few projects support REL.

I will *NOT* be bug-for-bug compatible with this in uIEC/sd2iec.

Right now, I'm implementing it for the native FAT16/FAT32 FS, so the 
Position translates into a fseek to the correct byte in the file. 

There's na unintended side benefit to implementing all of this DOS stuff 
on a different controller.  I have learned so much about CBM DOS.
