+= and -=

-----------------------------------

Just a quick question about the language...
I've come across people using += and -= in their programs. I couldn't find any answers online or on the site, so could anyone tell me what it does?

Those are accumulate operators. They say "add everything on the right to the variable on the left".

The statement x += 5 is equivalent to x = x + 5.

RE:+= and -=

-----------------------------------

in Turing that represents 'not equal to'. It's the same as writing 'not='. Most other languages use ! as the not operator.
