示例1: getArraysizeInBracket

  // eval() no longer performed before check and label
  // returns false if error; UNKNOWNSIZE is not an error!
  bool NodeSquareBracket::getArraysizeInBracket(s32 & rtnArraySize)
  {
    bool noerr = true;
    // since square brackets determine the constant size for this type, else error
    s32 newarraysize = NONARRAYSIZE;
    UTI sizetype = m_nodeRight->checkAndLabelType();
    if(sizetype == Nav)
      {
	rtnArraySize = UNKNOWNSIZE;
	return true;
      }

    UlamType * sizeut = m_state.getUlamTypeByIndex(sizetype);

    // expects a constant, numeric type within []
    if(sizeut->isNumericType() && m_nodeRight->isAConstant())
      {
	evalNodeProlog(0); //new current frame pointer
	makeRoomForNodeType(sizetype); //offset a constant expression
