Found one of those in the stacks of papers from my father's time at IBM. Funny how paper-based information technology was back then - the first thing that comes to mind are the punch cards, but also later program listings were printed out a lot.

We used stacks of "endless paper" core dumps / assembler listings when painting rooms, as you could just unfold a huge stack of paper to protect the floor from paint splatters.
