Side Scrolling + wait command

Does flash have a wait command?
i have this code here

 targ._x = targ._x - 2.500000;
if (targ._x <= -350)
{
targ._x = 344;
} // end if
   
}

it scrolls targ from right to left and when targ gets to -350 it restarts by putting targ clip back at 344 (start point)

my Q is does flash have a wait command? because i want to stop the side scrolling when the targ gets to -100 then wait a few seconds the nrestart scrolling
