Thread: help with errors...

im working on a a scripting language...called EASL (Easy Ass Scripting Language) just for learning.

Code:

// Main.cpp
#include "VirtualMachine.h"

using std::vector;

void main()
{	 
	VirtualMachine VM;

	vector <Instruction> InstrList;

	InstrList.push_back(Instruction(op_hello));
	InstrList.push_back(Instruction(op_hello));
	InstrList.push_back(Instruction(op_end));

	Script script(InstrList);

	int scriptId = VM.Load(script);

	VM.Execute(scriptId);
}

Code:

// VirtualMachine.h
#ifndef VirtualMachine_H__
#define VirtualMachine_H__


#include <iostream.h>
#include <vector>

using std::vector;

enum OpCode
{
	op_hello,
	op_end
};


// The Basic Instruction
class Instruction
{
	private:
		OpCode code;

	public:
		Instruction(OpCode _code) { code = _code; }
		OpCode Code() const { return code; )
};

// The Basic Script, a vector of instructions...
class Script
{
	private:
		vector <Instruction> instrList;

	public:
		Script(const vector <Instruction> & _instrList) { instrList = _instrList; }
		const Instruction *InstrPtr() const { return &instrList[0]; };
};

// Basic Virtual Machine to process commands
class VirtualMachine
{
	private:
		// pointers for non-modifying dynamic references
		typedef const Script		*ScriptRef;
		typedef const Instruction	*InstrRef;

		// data members
		vector <Script> scriptList;
		ScriptRef	scriptPtr;
		InstrRef	instrPtr;
		InstrRef	instr;
		int			scriptCount;

		// utilities
		int AddScript(const Script &script) 
		{ scriptList.push_back(script); return scriptCount++; }
		void SelectScript(int index)
		{ assert(index < scriptCount); scriptPtr = &scriptList[index]; 
			instrPtr = scriptPtr->InstrPtr(); }	

	public:
		VirtualMachine() 
		{ scriptPtr = 0; instrPtr = 0; instr = 0; scriptCount = 0; }
		void Execute(int scriptId);
		int Load(const Script &script) { return AddScript(script); }
};

//Implementation of VirtualMachine::Execute
void VirtualMachine::Execute(int scriptId)
{
	SelectScript(scriptId);
	instr = instrPtr;
	
	while(instr)
	{
		switch(instr->Code())		
		{
			case op_hello:
				cout << "Hello World." << endl;
				instr++;
				break;
			case op_end:
				instr = 0;
				break;
			case default:
				cout << "Command is invalid dumbass." << endl;
		}
	}
}


#endif

These are the errors i get in VC 6:

I dont see anything thing wrong with the code. I know i'm overlooking something. Two head are definetly better than one.

Thanks!
