|=

Can someone explain what the |= operator does or link me to a page with a description?

Thanks!

Well you know that += and -= are of the form:

x += y;
x = x + y;

Same deal:

x |= y;
x = x | y;

The | operator is the bitwise or:
0 | 0 = 0;
1 | 0 = 1;
0 | 1 = 1;
1 | 1 = 1;

0101 | 0111 = 0111;
0100 | 1100 = 1100;

Etc... There are many tutorials on bitwise operators.

Ahh, gotcha.
