Hi, fellows! Do I need spaces? Examples:

a=b+c VS a = b + c
load object "a",b VS load object "a", b
etc...

The compiler will complain if you are missing important spaces. Everything you posted should work fine. It is only commands with spaces in (which I hate btw!) and spaces before and after commands that matter. Mathematical and bitwise operators don't care about spaces.

You only "need" spaces where they are part of keywords (ie. make_object_sphere) and as separators between expressions / etc. They are not necessary as part of expressions, between commas in a function call or even after the ":" (multiple statements per line) token. I find it makes your code a lot more readable if you do use them as such though, as do many other people I'm willing to guess.
Still it is up to personal preference; some people like to use them whereever there are brackets as well (ie. green = rgb( 0, 128, 0 )) but I never write code like that. It may improve readability a bit, but it's inefficient to write. So in conclusion, you do as it best suits you
If other people are to read your code you should agree on a style that everyone will use to make all code equally readable to all involved parties.

@Rudolpho
Now that you mention "personal preference", I have actually started writing assignments like this, var= x, and equivalence testing like this, var =x, I think it is nicer too read this way.

Thanks to all! Also Libervurto mentioned "testing". I'd prefer to put a rem after the test line, but encountered compiler issue:

doesn't compile, but


does. Is that something wrong with EOL characters or something?

try a colon before the REM, it's probably not treating REM as a delimiter

Yeah, it works! But with commentary in english (rem like this) it works without colon. So there goes another probable issue: what about non-english letters in the code? In strings, comments, etc. How do they compile? Compatibility..?

Also why "\\" works if it is not official?

Good question, I have no idea. From what I remember, special characters could be used in strings, but not for variable names.

Because

Not usually, though I've found the compiler is picky with too many spaces in UDTs. Especially tabs.

Perfomance loss?

What? No, more spaces does not decrease performance. It just wouldn't compile.

Your opinion and the incorporation of thermal noise equations in a high-voltage oscillator circuit are mutually equivalent in relevance.
