使用flex和bison

/*

playfile(ds,1)
typedef struct 
{
	int itoken;
	char stoken[100];
} token

token tokenarray []=
{
	{60001,"DDSTR1"},

}

Ddstr1 total0




问题：

  	sf($sys_dtmf=="*") 结果为真
		{
			yingliang = yingliang + 1;
			if(yingliang >= 7)  结果又为假，覆盖危险 我们要用堆栈来解决这个覆盖问题
			{
				yingliang = 7;
			}
			confplayfile(songfile,2,yingliang);
			goto m_callerswitch;
		}
		elsesf($sys_dtmf =="#") 
		{
			yingliang = yingliang - 1 ;
			if(yingliang < 0)
			{
				yingliang = 0;
			}

			confplayfile(songfile,2,yingliang);
			goto m_callerswitch;
		}
		else
		{
	
			sql= "select b.ringfile " 
			+ " from taga_talkin_beijing_holding_ring a ,taga_talkin_beijing_ringindex b "
			+ " where  a.ringid = b.ringid  and a.recordindex = " +$sys_dtmf +
			 " and a.userid = " + userid ;
			sqlselect(connid,sql);
			int i = getaffectedrow();
			if(i == 0)
			{
				 songfile = defaultring;
			}
			else
			{
				 songfile = getfieldvalue(0);
				
			}
			confplayfile(songfile,1,yingliang);
			goto m_callerswitch;
