运行的结果为什么会有“小花“？

哪位高手先运行一下试试看，我运行的结果是有一个小花，还有一行不该出现的文字
是这样的：
假如说输入的是123vabn
运行的结果为：
please input the some chars.....
result is....
123vabn；就在这个地方一个小花，还有please input the some chars.....

下面是按我的习惯作了修改，为什么在字符串里有回车换行你还要CRLF，而在输入了字符以后又不CRLF。在BUFS后面必须加'$'才能正常结束，还有MOV YE,BL MOV BL,YE我觉得是重复的。另外输入长度最多也就10个字节，没有必要用双字也没有必要在转BIN时除于100。
