This really brings back memories of programming RPG for the AS/400 in school, almost 30 years ago. Since we did not actually have access to an AS/400, all programming was done on printed pieces of paper.
The paper was formatted in numbered rows/columns, where for example a loop was created by putting the letter R in exactly column 5 and nowhere else (something like that, thankfully I've forgotten the details).
It all felt like one step above punched cards.
Our "programs" were never actually executed, our professor also did not have access to an AS/400.
Anyway, just saying, column and row based programs are a welcome trip down memory lane, let's keep it there.
