I don’t agree. There is nothing wrong with using this:
put x into field y We can’t say that real programmers use this: set the text of y to x I see nothing wrong with teaching the first, before showing it is the same as the latter. Indeed, the hello world is this: put “Hello World!” into field “Greeting” Though I have never had a kid use “Hello World!” even the first time. OK, maybe a big sister.
