In computer programming I will use American language, even if the documentation is Canadian (I am Canadian, so I write Canadian documentation even though the commands in the program itself will be American). However, you can also have programming languages with abbreviated keywords or no keywords, which is also sometimes suitable. If there are keywords, I will always do it in American. (And when writing music, I will write all of the notation in Italian, even though I do not speak Italian. If I don't know the Italian word for something, I will ask someone who does know, and write that.)
