Seeing a programming language in your native language after working with English ones, you discover that it looks and sounds pretty ridiculous. My belief is that the native language is ingrained on a low level in the brain, so it's decoded ‘in the hardware’ and directly invokes meanings and associations, whereas a second language goes through at least some level of conscious processing. The very same way, I'm physica…
That's probably the reason. I'd bet after working for the same time with 1C, you (or I, for that matter) would completely ignore keywords and names being in the Russian language. You'd die from the boredom much earlier though, but that's a different matter)
Btw, END IF is as weird as КОНЕЦ ЕСЛИ.
