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.
