请老师帮忙把这段转换为wh6可以使用的语句 (文华财经WH6赢顺V6.7)

参数M1、M2、M3、M4请自行定义，改写参考

MA1:MA(CLOSE,M1);
MA2:MA(CLOSE,M2);
MA3:MA(CLOSE,M3);
MA4:MA(CLOSE,M4);
CURRBARSCOUNT:=DATACOUNT-BARPOS+1;
DRAWTEXT(CURRBARSCOUNT=M1+1,MA1,'扣');
DRAWTEXT(CURRBARSCOUNT=M2+1,MA2,'扣');
DRAWTEXT(CURRBARSCOUNT=M3+1,MA3,'扣');
DRAWTEXT(CURRBARSCOUNT=M4+1,MA4,'扣');
