Text Field - alignment with sigle textfield

Friends,

Lets say i have a AS code

a.text = "OOO " + "BRO
";
a.text+= "iii " + "BRO
";

If we type in a notepad then it is proper

But in the .swf , it’s like the below image.

It is clear in a Flash text field each character uses different width. So it doesn’t line up the text properly. I mean, like in the example, second line “BRO” is a bit left as compared to “BRO” in first line. Is there any setting/code that i can use so that it displays like above image of the notepad where each character consumes same amount of screen space so that character in each line lines-up properly.

Thanks!
