A2AWith the advent of online form filling, the idea of using all capital letters has probably fallen into disuse. But for most of my life, ALL paper forms have required capitals. This is default mode for handwritten forms, in my experience, and I do it automatically. You are probably a lot younger than I am!It stems from the fact that many people have bad handwriting and the effort of slowing down to use all capitals on a form makes the replies more legible. If the instruction u201call capitalsu201d appears on an online document, then it has probably been adapted from an earlier document, which used to carry handwritten replies, and nobody has bothered to change it.And yes, it means everything: your name and address are the the most important items on the form.Just go along with it: it's not an unreasonable request!
