Type the following commands, on separate lines, and then press ENTER:
  sp_password @old = null, @new = 'complexpwd',  @loginame ='sa'
  go
     
where i should replace "complexpwd" with the new strong password. but i don't know how to jump to a new line without pressing ENTER.....can you please help me
