MAX_FD_INDEX = 12
MAX_FD_VAL = 8 ; we have 8 IOCBs
ft_entrylen = 4 ; length of table entry (it's not sufficient to change here!
; the code sometimes does two bit shifts to multiply/divide by
; this length)
ft_usa = 0 ; usage counter
ft_iocb = 1 ; iocb index (0,$10,$20,etc.), $ff for empty entry
ft_dev = 2 ; device of open iocb (0 - device not remembered, eg. filename specified)
ft_flag = 3 ; flags
; lower 3 bits: device number (for R: and D:)
