Format
A | B
Returns
The binary “or” of A and B.
A and B must be between 0 and 2**24 - 1, giving an effective width of 24 bits.
If A and B are lists, the result is a list containing items that are in either list. list(1,2) | list(2,3) is equivalent to list(1,2,3). The items from A come first in the result, followed by any extra items from B.
If A is an icon or /icon datum, it is blended with B which can be either a color or another icon. Unlike the + or & operation, the result is transparent only in places where both icons were transparent.
