有两段脚本，看不懂是什么意思，请高手指点：
WORD bHelp1,bHelp2;
char* acttag;
acttag=GetTagChar("MOTOR_ID"); //Return-Type :char*
bHelp1=GetTagWordWait(acttag); //Return-Type :BYTE
bHelp2=bHelp1&(0xFFFFFFFF^1);
SetTagWordWait(acttag,(WORD)bHelp2);


WORD bHelp1,bHelp2;
char* acttag;
acttag=GetTagChar("MOTOR_ID"); //Return-Type :char*
bHelp1=GetTagWordWait(acttag); //Return-Type :BYTE
bHelp2=bHelp10x1;
SetTagWordWait(acttag,(WORD)bHelp2);
