readme for NUT v1.0

This is a simple version of NUT (without global variables). The compiler is "nut.exe" which takes standard input as NUT language source file and produces "a.obj" object file suitable to execute under "nsim.exe" the simulator.

Example session

c:>nut < quick1.txt

a lot of output appears on the screen. They are the "n-code", the intermediate language. You can read about it in \doc\n-code.txt. The compiler will produce "a.obj". Then, run it using "nsim".

c:>nsim < a.obj

(fun.2.2 (do (put.1 (new lit.20 ))(call.408 get.1 lit.20 )(call.466 get.1 lit.20
)(call.354 get.1 lit.0 lit.19 )(call.466 get.1 lit.20 )))
