Right. 4DOS is almost overkill and does many many things.

Right, which is good for shell macro glue wrapping (or whatever you
want to call it). Also good for bigints (arbitrary precision). It's
portable too.

If someone just wanted a simple calculator, various tools exist, not
to mention CALC387, which is only 1024 bytes (requires FPU). See

P.S. ReactOS has a CMD shell clone (GPL? LGPL?), though I'm unsure how
fully functional it is. It actually was partially based upon FreeCOM,
but probably they didn't bother sticking to strict ANSI C
compatibility. (Seems to need CMake to build, which doesn't have a DOS
port. Blindly guessing, but it probably requires MinGW.)
