Last week I wrote few simple Visual Basic codes at home for solving a
problem. But when I tried to run them in my school's lab, it warned that it
will not run the macros. I ended up re-entering the whole solution process
over few excel worksheets.

Now, if I have these Visual Basic codes written, I was wondering if you
would suggest an alternate way (may be by creating an attachable library)
that I can follow so that I can solve problems using codes and run them in
the school's lab?
