error: identifier "byte" is undefined.
A friend gave me some code to add to my project but I fail to compile it, probably because of the definition of byte(or BYTE, I don't know) as a variable. Here is the code that won't compile, and below are the errors from the compiler.
parser.cpp
Code:
//-----------------------------------------------------------------------------
// Parser

#include "parser.h"
char Parser::token[MAXTOKEN]; // buffer for tokens
int Parser::scriptline;
const byte *Parser::buffer;
const byte *Parser::buf_start;
const byte *Parser::buf_end;
void Parser::StartParseBuffer(const byte *buff, const int size)
{
buf_start = buffer = buff;
buf_end = buff + size;
scriptline = 1;
}
void Parser::StartParseString(const char *string)
{
buf_start = buffer = (byte *) string;
buf_end = (byte *) string + strlen(string);
scriptline = 1;
}
// if crossline is false, GetToken returns false when a line break is found
// GetToken(true) returns 0 only if end of file
// GetToken(false) returns 0 if line break or end of file
bool Parser::GetToken(bool crossline)
{
char *token_p;

PS: If you find any other mistake or anything that needs to be changed(including a way to get rid of the goto) please let me know.
