I think OpenDOS should, by default, be compatible with MSDOS (really with PKZIP), but have an option (int 21h, AX=370?h) to set a bitmask to make the int21h/13h call behave sensibly but incompatibly by specifying a bitmask. By the way: I recall from the dim and distant past that using the FCB delete with ????????.??? was the fastest way to delete a whole directory full of files; is this actually still the case in MSDOS etc? ------------------------------------------------------------------------------- Mark Aitchison, Physics & Astronomy \_ Phone : +64 3 3642-947 a.h. 3371-225 University of Canterbury, (/' -------------------------------------------------------------------------------
