How Does The Break Statement Work?

For the first time, I'm attempting to write a small Javascript program
using one on the online reference sites. I need some confirmation as
to the behaviour of the break statement.

In the following code:

for ( row = 0 ; row <= 7 ; row++ ) A <----
{
for ( col = 0 ; col <=7 ; col++ ) B <----
{
if ( check ( row, col ) == "pass" )
break ;
}
}
}

Where will control pass to once the break statement is executed?
Will it continue with the first 'for' statement (A) or the second (B)?

Also my 'check' function needs to pass an indication as to it's
success or failure. It does it by:

return ( "pass" ) ;

Am I doing it correctly?

Any links to useful reference sites would be welcomed.
