You don't want to even consider using % and its kin to reference
previous execution lines in a package file. That would lead to
extremely unpredictable performance. If you did it, the executed
line would vary according to when the package was loaded and
when the function that made the reference was executed.

Mathematica has a variety of methods for performing loops. Paste
the following in to the Documentation Center search box for a
basic description of loops and control structures.
