Thread: Print problem

I'm trying to figure what the problem might be with this. It is suppose to print a list of the tokens for what ever file is input but it won't.

Code:

#include <iostream>
 #include <fstream>
 #include <string>
 #include <ctype.h>

 using namespace std;

 typedef enum { ENDFILE, ERROR,IF, THEN, ELSE, END, REPEAT, UNTIL, READ, WRITE,ID, NUM,
      ASSIGN, EQ, LT, PLUS, MINUS, TIMES, OVER, LPAREN, RPAREN, SEMI
     } TokenType;

 ofstream wfile;

 void printToken( TokenType token, char arg[], ostream &outFile)
 { switch (token)
   { case IF:      outFile << "reserved word: " << arg << endl; break;
     case THEN:    outFile << "reserved word: " << arg << endl; break;
     case ELSE:    outFile << "reserved word: " << arg << endl; break;
     case END:     outFile << "reserved word: " << arg << endl; break;
     case REPEAT:  outFile << "reserved word: " << arg << endl; break;
     case UNTIL:   outFile << "reserved word: " << arg << endl; break;
     case READ:    outFile << "reserved word: " << arg << endl; break;
     case WRITE:   outFile << "reserved word: " << arg << endl; break;
     case ASSIGN:  outFile << ":=\n"; break;
     case LT:      outFile << "<\n"; break;
     case EQ:      outFile << "=\n"; break;
     case LPAREN:  outFile << "(\n"; break;
     case RPAREN:  outFile << ")\n"; break;
     case SEMI:    outFile << ";\n"; break;
     case PLUS:    outFile << "+\n"; break;
     case MINUS:   outFile << "-\n"; break;
     case TIMES:   outFile << "*\n"; break;
     case OVER:    outFile << "/\n"; break;
     case ENDFILE: outFile << "EOF\n"; break;
     case NUM:     outFile << "NUM, val= " << arg << endl; break;
     case ID:      outFile << "ID, name= " << arg << endl; break;
     case ERROR:   outFile << "ERROR: \n"; break;
     default:      outFile << "Unknown token: \n",token;
     arg = NULL;
   }
 }

       }
