Question 1: 
==================================================

UNKNOWN1 = 

CDefs ~ CDef {"." CDef}.
CDef ~ CN  Ps.
Ps = P {"," P}.
P = CN.
CN = Ident.
Main = <s> String.



UNKNOWN2 =

cg.traverse(this,"from CDefs to CN", new Visitor(){
  int c;
  void start(){c=0;}
  void before(CN host) {c++;}
  void finish() {System.out.println(c);}
});

OR

List l = cg.gather(this,"from CDefs to CN");
System.out.println(" Found " + l.size() + "CN-objects");


Question 2: 
==================================================

UNKNOWN1 = 
X = "x" Y.
Y = "y" Z.
Z = "z".





UNKNOWN2 =
x y z

UNKNOWN3 =

from X to Z 

or 

from X via Y to Z

Question 3: 
==================================================


UNKNOWN1 = PointCut_List

UNKNOWN2 = PointCut

UNKNOWN3 = PointCut

UNKNOWN4 = AndOrExp

UNKNOWN5 = OpPCExp

UNKNOWN6 = OpPCExp

UNKNOWN7 = Nonempty_PointCut_List

UNKNOWN8 = PointCut

UNKNOWN9 = CFlow

UNKNOWN10 = PointCut

UNKNOWN11 = NotExp

UNKNOWN12 = CFlow

UNKNOWN13 = This

UNKNOWN14 = AspectJFragment

UNKNOWN15 = PointCut_List

UNKNOWN16 = PointCut

UNKNOWN17 = This

UNKNOWN18 = PointCut

UNKNOWN19 = AndOrExp

UNKNOWN20 = OpPCExp

UNKNOWN21 = This

UNKNOWN22 = OpPCExp

UNKNOWN23 = PointCut

UNKNOWN24 = PointCut

UNKNOWN25 = NotExp



Question 4: 
==================================================

There are several variations that are correct.

UNKNOWN1 = 
 List

UNKNOWN2 =
 AdviceKind <lhs> PCList(ArgDecl) ":" <rhs> PCExp "{" "}" ";".

UNKNOWN3 =
 AdviceKind   CHOICE: match with UNKNOWN2 AdviceKind

UNKNOWN4 =
 Before | After

UNKNOWN5 =  "before"

UNKNOWN6 =  "after"



Question 5: 
==================================================

UNKNOWN1 = 

Visitor v1 = new Visitor() {
   void before(Variable host) {
     System.out.println(host.get_ident());
   }
};

System.out.println("left-hand-side");
cg.traverse(this,"from AspectJFragment via {-> *,lhs,*} to Variable",v1);

System.out.println("right-hand-side");
cg.traverse(this,"from AspectJFragment via {-> *,rhs,*} to Variable",v1);
