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.
