When you begin your work in Macrodata Refinement, you will be assigned a macrodata file. This selection has been made carefully by your superior.

Turn on your computer. Sit back and watch as your computer cycles through its boot up process. Do not be alarmed by the many lines of text appearing on your screen. This is completely normal. Your computer is simply loading the Macrodata Refining Program.

Now, watch as the iconic logo of our beloved company spins onto the screen. This is all part of the computer's boot-up sequence.

After the logo disappears, a small blinking cursor will appear in the upper left of your screen. Using your keyboard, type the name of the file on which you will be working and then press ENTER.

If you have not been assigned a file, or if you cannot remember the name of the file you were assigned, ask your supervisor to refresh your memory.

After pressing ENTER, your computer will load a file rolodex. Using your ARROW keys, page UP or DOWN until you locate the tab that shows the name of the file you were assigned. CLICK on the rolodex card.

After opening your file you will be met with a sea of numbers that seem to stretch endlessly in all directions.

Over time, certain clusters of numbers will start to make them feel a certain way.

There are 4 categories of numbers, each of which elicits a different feeling. A refiner's job is to fill each of 5 bins evenly with the 4 kinds of number clusters.

Once every bin is properly filled, the file is 100% refined and the job is done.

Files worked on by the refiners most recently employed by Macrodata Refinement in the Kier flagship office of Lumon:
