Hey all,

while reading the forum i found code where i can't understand the operation.

set |=  state;
set &=~ state;

( full src code: https://www.mql5.com/en/forum/222650 )

What is "|=" and "&=~" doing ?

Thx && Regards

Thank you for you answer. I was reading the articles before and dont get the sense out of it. Why is he using this way ?

Because it is simpler to write and can't have typo.

V2i5i7i3o2p2 = V2i5i7j3o2p2 | 4; // This line has a typo

V2i5i7i3o2p2 |= 4;               // This line can't

Same as

V2i5i7i3o2p2 = V2i5i7j3o2p2 + 4; // This line has a typo

V2i5i7i3o2p2 += 4;               // This line can't

++V2i5i7i3o2p2;                  // One is a special case.
