Here is a code

extern NodePtr  CreateNode(NodeType, ...);
extern NodePtr  ReplaceNode(NodeType, NodePtr); 
extern NodePtr  MergeSubTrees(NodeType, ...); 


            ...................


NodePtr   rootNodePtr = NULL; /* pointer to the root of the parse tree */
NodePtr   nodePtr = NULL; /* pointer to an error node */


                         ...........................

NodePtr   mainMethodDecNodePtr = NULL;

                   ................
