4 ; offsets and defines for fdtable (internal use only)
7 MAX_FD_INDEX = 12 ; max. # of open fds
8 MAX_FD_VAL = 8 ; we have 8 IOCBs
10 ft_entrylen = 4 ; length of table entry (it's not sufficient to change here!
11 ; the code sometimes does two bit shifts to multiply/divide by
14 ft_usa = 0 ; usage counter
15 ft_iocb = 1 ; iocb index (0,$10,$20,etc.), $ff for empty entry
16 ft_dev = 2 ; device of open iocb (0 - device not remembered, eg. filename specified)
18 ; lower 3 bits: device number (for R: and D:)
19 ; bit 3 - seeking supported by DOS/disk combination
20 ; bit 4 - indicates a fd opened by the program as apposed to the
21 ; inherited ones from program start (fd 0 to fd 2)
