I can visualize many beginners doing this as a first en.wikipedia.org/.../Hello_world_program the poor sods are not going to get an error message, the code will just hang.
I know why, but consider it bad that you get a hang, not an error message, especially when you feebly try do run Keil for the first time. Yes Please read the manual should cover it, but did you Please read the manual the first time you started C?

The fact that you had a hard time with it doesn't mean other beginners will have a hard time with it either.
if you had read the post you responded to fully oh, well, if you did, you would not have had an opportunity for a snide remark, you would have read:
"BTW, I, of course, discovered this by 'forgetting', but, as opposed to a beginner it only took me a minute to go DOOH"
