1. MobileASM:
I developped this application with
Java(TM) ME platform SDK 3.0, EA.
And it is very simple software to
execute assembly as script. However,
I make it in a haste and the FLAGS
is confusing and I have not corrected
the error.

   // 1+2+3+...+100
   mov eax,0
   mov ecx,100
   add eax,ecx
   dec ecx
   ja  3
   print "1+2+3+...+100
   print eax
   end

2. ExpressionCalc:
I write it without using regex of Java
to build an own code interpreter. And
I use the CalcTree to do calculation
for a complicated expression and SymbolTable
supports to hold varibles.

   SymbolTableNode stn;
   SymbolTable st;
   CalcTree ct;
   LineCodeStream lcs;

   st = new SymbolTable();
   ct = new CalcTree();

   // declare variables
   stn = st.add("hello", null);
   stn.data = Double.valueOf(20.0);
   stn.type = 0;
   stn = st.add("world", null);
   stn.data = Double.valueOf(10.0);
   stn.type = 0;

   // declare functions
   stn = st.add("sqr", null);
   stn.data = Integer.valueOf(1); // function id
   stn.type = 1;
   stn = st.add("cube", null);
   stn.data = Integer.valueOf(2);
   stn.type = 1;
   stn = st.add("double", null);
   stn.data = Integer.valueOf(3);
   stn.type = 1;

   // try an expression
   lcs = new LineCodeStream("hello+cube(world) - (world + 2)*sqr(2) - sqr(cube(double(2)))/hello");
   // TODO: proccess every token from lcs.getWord()
   // TODO: and add tokens to calculating tree
   double _val = 0.0;
   _val = calcTreeValue(ct.getRoot(),st);
   System.out.println(lcs.getLineCode() + " = " + _val);
