  1) You could pass a pointer to the File_Type.  Or make an array
of File_Type elements and pass an index to Start_Lines.
  2) When an Ada compiler complains about something, it's wise to
think hard about whether you really want to do what you wrote.  In
this case, after "end Start_Lines;" you will have two different
tasks reading/writing/closing the same file:  the Phone_Line task and
its caller.  That's certainly a situation that's highly likely to get
you into trouble.  If the caller doesn't actually do anything but
open or create the file it passes to Phone_Line, perhaps it should
instead pass the name and let Phone_Line open/create its own
This_Simulation_Data file.
