compiling error!

Hi all..

i have this code here..

Code:

#include <windows.h>
#include <iostream.h>
#include <tchar.h>
//convert the string to number
//udata is string
//udatalen is length of string
//base is numerical base eg. for decimal it is 10
// for hex it is 16
//largest base supported here is upto 36

int __fastcall StrToNum(const TCHAR *udata, int udatalen, int base)
{
	long index;
	const TCHAR numdigits[] = TEXT("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
	long digitValue = 0;
	long RetVal = 0;
	TCHAR digits[sizeof(numdigits)+1];
	TCHAR *dataVal;
	TCHAR data[512] ;
	//copy the data to our variable
	_tcscpy(data, udata);
	//convert it to upper case
	_tcsupr(data);
	ZeroMemory(digits, sizeof(digits));
	//copy the number of digits supported by base in digits
	_tcsncpy(digits, numdigits, base);
	for(index = 0; index < udatalen; index++)
	{
		//is the number there
		dataVal = _tcschr(digits, data[index] );
		if(dataVal != 0 )
		{
			//if it is subtract where to start point
			digitValue = long(dataVal - digits);
			//increment Retval with digitvalue
			RetVal = RetVal * base + digitValue;
		}
	}
	//return the result
	return RetVal;
}

TCHAR* __fastcall NumToStr(TCHAR *RetData, long number, int base)
{
	long index = 0;
	const TCHAR numdigits[] = TEXT("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
	long digitValue = 0;
	TCHAR digits[sizeof(numdigits) + 1];
	TCHAR RetVal[512];
	TCHAR CurVal = 0;	
	ZeroMemory(RetVal, sizeof(RetVal));
	// only base supported are from 2 to 36
	if(base < 2 || base > 36 ) return NULL;
	ZeroMemory(digits, sizeof(digits));
	_tcsncpy(digits, numdigits, base);
	while(number)
	{
		digitValue = number % base;
		number = number base;
		RetVal[index++] = digits[digitValue];
	}
	//since string we have got is in reversed format
	//eg 100 will be 001 so we have to reverse it
	//and put the value in our variable
	ZeroMemory(RetData, _tcslen(RetVal)+1);
	int i = 0;
	for(index = _tcslen(RetVal) - 1; index > -1; index--)
	{
		//start reversing
		RetData[i++] = RetVal[index];
	}
	//return the result
	return RetData;
}

//our main function
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
	TCHAR Data[128];
	ZeroMemory(Data, sizeof(Data));
	//convert a number to string
	NumToStr(Data, 1123, 10);
	//now again convert string to number and see the result
	cout << StrToNum(Data, _tcslen(Data), 10) << endl;
	return 0;
}

but when i compile it this error msg appear to me :
syntax error : missing ';' before identifier 'base'

i've cheaked the place where it said that the ";" is missing but it's not!

so pls if any1 can help me..

and thank you very much

something else is missing

number = number / base;

change following lines to be closer to C++ standard

Code:

#include <iostream>

	std::cout << StrToNum(Data, _tcslen(Data), 10) << std::endl;

It would help if you could indicate which use of base in your code (there are many) which is causing the problem.
