I'll save you another 224 bytes soon... f_boff and f_sector aren't necessary to keep resident. More savings (eliminating f_back, transforming (f_dirstart (4 bytes),f_diroff (2 bytes)) into (f_sector (4 bytes), f_diroff (1 byte), and maybe even using SFT's to store resident info) are more complicated. > > if (new_diroff == 65535) > > Borland C++ complains here. Change the constant to 65535UL (see patch > below). ok, I'll make it 65535U then, or maybe 0xffff. Then the U is not necessary.
