You don't have to claim the code if nobody knows it exists in the first place. It was not anything I ever meant to show anybody. Just small utilities for myself, meant to actually improve my productivity.
I practiced highlighting all the fields, switching apps, and pasting the data. You could only play back at maybe 3x original speed. Then I started my macro running. I had estimated that I could have done it manually in about three days; the macro would do it in about 30 hours and not screw up any of the data along the way. Told the supervisor what I'd done and asked to be paid for two. She said yes and offered me a job on the spot; too bad I was starting med school in a month.
I wrote a program from scratch on my TI-82 to calculate the answers and my math teacher said "You wrote the program yourself, so you can use it during the exams. You still have to show your work manually, but it sounds great to check your work."
This was a pivotal moment in my path to becoming a software engineer. :)
