2 easy questions

ADDITION
I don't understand exactly whats going on here.
If I do 37+79, I get the result 116, which is Fine.

If I do 037+079, I get 110, which I don't understand.
So next I tried...
alert("037+079="+037+"+"+079);
which gives 037 as 31, and 079 as 79, hence the 110.
I thought it could be octal at first, but it isn't, and
it's not hex either.
Can someone explain why 037 is 031, and 079 is 079?
Thanks

Secondly
DOUBLE CLICKING ON TEXT FIELD
I had a question, which said when double clicking on a text field,
which event occurs.
Well its either Focus or Select.
But I then wrote a program, and when you double click a text field...
Sometimes it highlights, and its a SELECT, but other times, its just a
FOCUS.

I guess the answer is FOCUS, but that is a vague question in my opinion.

Thanks very much if you can help with either of these.

9 is not an octal digit.
