[求助]：急！ads_command命令问题

pckite

我想显示某个范围的内容，但是以下的代码，运行不出效果？错在哪里了？
char buf1[256],buf2[256];
sprintf(buf1,"%.2f,%.2f",point1[0],point1[1]);
sprintf(buf2,"%.2f,%.2f",point2[0],point2[1]);
int result=ads_command(RTSTR, "ZOOM",RTSTR,"W",RTSTR,buf1,RTSTR,buf2,0) ;

该程序本身好象没有错，是否该段程序处在不适当的位置，导致ads_command()无效？

int result=ads_command(RTSTR, "ZOOM",RTSTR,"W",RTPOINT,point1,RTPOINT,point2,0) ;
