About
-----

This Calculator emulates a HP35.

To compute 3*(4+5) type : 3 enter 4 enter 5 + *
     
Using HP35
----------
There are 4 stack-registers: X, Y, Z and T. You see always the X-register.

Enter pushes x to Stack.

Computing with 2 arguments pulls x and y and stores in X. t is copied to Z. So you have the possibility of multiple use.
 
Computing with 1 argument replaces x. Enter is not necessary.
