    I posted a few questions to the list a little while back.  I received
    help from one brave individual named Charles Sandmann.  Thanks.  He
    sent mail to me at next1 instead of just scri (mailer problems). Well,
    as of today my mail should, hopefully, work again.

    I was trying to get the graphics to work using a demo called GRTASK.
    The solution is to get one of the patched versions of GO32 available.
    The next trick: use the *.grn drivers with it.  All others will cause
    a severe halt.  Thanks again Charles!

    I also asked about getting Objective-C going with DJGPP.  Again,
    due to the mailer problems, most people probably bounced mail to me.
    Anyways, I copied gcc from  The stuff appeared to 
    be there.  There was even a makefile for NDMAKE under GCC.  However,
    the objc directory appeared to be missing a file called xforward.c.
    I think the lack of it is causing the linker errors I am getting.
    Anyways, I will check again tonight, but if someone has some tips
    for installing it, I would appreciate it.

    My final question is about interupts.  I would like to get interupts
    from the timer and from a soundblaster or from a printer port.
    Could these interupts be handled in 8086 mode (if that is the regular
    pc mode, I think it is real mode, though; so could they be in real mode?)
    Or do they have to be handled in protected mode.  If so, what would
    some general pointers be in building such routines.

    Finally, when I tried using gcc on one program, I had the GO32
    variable set to mono 1rm 2rm with my appropriate driver.  There
    was a ton of garbage and code being output to the mono monitor.
    I didn't know if this was a bug or a feature so I thought I would
    mention it to the list.

   Take it easy,
