Hi FreeDOS devel people,

as I was wondering "how small is that popular newish
scriptish language, Lua, in DOS?" recently, Rugxulo
put together a few files. Maybe you want to test :-)

Old Lua 4.0 in a 16 bit version:

www.ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/lua/4.0/

A test suite, see www.lua.org/tests/5.2/#basic is:

www.ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/lua/5.2.1/lua-5.2.1-tests.tar.gz

And fresh Lua 5.2.1 as DOS exe (94 kB UPXed) is at:

www.lua.org/ftp/lua-5.2.1.tar.gz

This answers a size question. Lite Rexx is smaller?

Some example Lua one-liners:

lua -e "print(42*42)"
lua -e "os.execute(\"mem /c\")"

The latter shows circa 445 kB free for Lua in DOSEMU
after Lua itself consuming 178 kB, Rugxulo says :-)

Another interesting question would be how 16- and 32-bit
compiles with OpenWatcom and DJGPP compare in performance.

Regards, Eric
