可能意外地导致意外访问。如果您指定一个 POINTER TO BYTE 到一个 POINTER TO [...] Int : POINTER TO INT; byte

类型变量 POINTER TO 理由：IEC 61131 [...] Temp : POINTER TO INT; pbyTemp : POINTER TO BYTE; END

类型变量 REFERENCE TO 理由：IEC 61131 [...] _int : REFERENCE TO INT; ref_dw : REFERENCE TO DWORD; END

接口的声明 检测声明 REFERENCE TO [...] REFERENCE TO ) 理由：接口 [...] _ref : REFERENCE TO ITF; // SA
