Hi Aitor,
Can I use this append with MS-DOS or in Win98se dos-box?
MS-DOS: In theory, unless there is a backdoor somewhere, this APPEND is implemented following RBIL and MS-DOS 6.22 help (except that the functions mentioned are not implemented, but I doubt that you have programs using FCBs?), and it should even be compatible with MS-APPEND, except with MS-APPEND 3.21 (but I recommend not to mix them).
I mention this of backdoors in particular because:
(a) MS-DOS 6.22 help does say that COMMAND's DIR is not affected by APPEND /X. FreeCOM DIR is not affected by FD-APPEND /X, even with no modification on the side of FreeCOM
(b) If you check RBIL, Int 2F/AX=AE01h it says that "APPEND hooks this call", and not just APPEND USES this call (as could be used to SET APPEND= in APPEND /E, for example). I haven't hooked this call, I don't know exactly why to hook this.
WindowsNT/XP: It seems that FD-APPEND works well under NT DOS Boxes, but you have to rename APPEND.EXE to other name (otherwise, the NT's APPEND is used).
Win98SE dos-boxes: I ignore what the effects of locally hooking int21h could be, I suppose there will be bigger problems if you run it on AUTOEXEC.BAT or WINSTART.BAT, but I haven't tested this. So if you test, please tell us :)
