DOS 386 TADS 2 distribution
---------------------------

Included here are versions of the TADS run-time and compiler that require a
386 (or better) processor to run.  They function exactly like their
standard DOS counterparts, but are faster and can use all the memory in
your machine, whereas the normal versions can only use conventional RAM and
runs in the slower "real mode".  If you have large games to run or compile,
and have at least a couple megs of RAM, you'll notice a big difference,
since these programs won't have to swap to disk as much.  Also, you
shouldn't ever have to use the -m option to set the cache size using the
compiler included here.

These versions run in protected mode and will coexist peacefully with
memory managers like QEMM and 386Max.  They were built using DJ Delorie's
GO32 DOS extender and were compiled with GCC 2.6.3.  A version of GO32 is
included in this archive.  The executables will look for go32.exe in your
path.  Hence, you'll need to put go32.exe in one of your program binaries
directories.  Once it's in your path somewhere, you can type "go32.exe"
from the command line to find out how much memory GO32 has available to it.

It may be the case that you have to define an environment variable or two
correctly before GO32 will work with your system.  You can add these to
your autoexec.bat, or put them in a separate .bat file that you run
explicitly (by typing the batch file's name at the DOS prompt) whenever you
want to use TADS:

	set GO32=nodpmi
	set GO32TMP=c:/

Because GO32 is a DOS extender, it can use hard drive space to give you
extra memory in addition to the physical memory you actually have.  This
means that you can compile or run TADS programs that would normally be too
large for your machine.  To make this work, however, you need to set the
GO32TMP environment variable mentioned above to the name of a drive that
has free space on it; for example,

	set GO32TMP=c:/

will tell GO32 to use drive C: for extra memory (also known as "swap
space").

GO32 has many more capabilities than TADS uses.  You can get a complete
GO32 distribution, including free software development tools, from
simtel20, or one of its many mirrors (oak.oakland.edu, wuarchive.wustl.edu,
ftp.uu.net).

I've included two versions of the compiler: one optimized for 486's and the
other for 386's.  If you haave a 486-based machine, use tadsc486.exe --- it
will be about 5% faster than the standard tadsc.exe.
