  I understand that the range syntax in loops implies that the loop variable is acting like an enumerated type which is not true for Big_Integers.

  What confused me is that I thought I had to convert the numeric literal (I'll have to go back and look at the package spec again to get this firmly understood.

  I have an another question about string slicing: I've tried (obviously incorrectly) to use a variable is one of the slice integers. Can this be done?
