I've waited awhile after seeing this but I'm still just getting a blank page,
is there supposed to be content there?  I was curious to compare the final
version with my code, which is (in part):

	/* Process the numeric string */
	for( value = 0, i = 0; i < strLen; i++ )
		{
		const int valTmp = value * 10;
		const int ch = byteToInt( str[ i ] ) - '0';

		if( ch < 0 || ch > 9 )
			return( CRYPT_ERROR_BADDATA );
		if( value >= ( MAX_INTLENGTH / 10 ) || \
			valTmp >= MAX_INTLENGTH - ch )
			return( CRYPT_ERROR_BADDATA );
		value = valTmp + ch;
		if( value < 0 || value > MAX_INTLENGTH )
			return( CRYPT_ERROR_BADDATA );
		}

Peter.
