我对过程定义理解不透彻，不知道这个END到底应该怎么修改？在线等待
[解决办法]
使用宏时，应该直接写宏名称，如果有参数，在名称后面加个空格然后写参数，各参数之间用逗号分隔。
call clear —— 这样的写法是调用函数，而clear是一个宏不是函数，应该把call去掉。
input_str MACRO str21,count3 —— 这样的写法是定义宏，在程序中使用时应该把MACRO去掉。
[解决办法]
宏定义是由一对宏汇编伪指令MACRO/ENDM来完成:其中宏名是符合语法的标识符,同一源程序中该名字定义惟一,宏可以带显式参数表:可选的参形表给出了宏定义中用到的形式参数,每个形式参数(哑元)之间用逗号分隔.
