Pipe or vertical bar ("|" or "¦") is the name of the ASCII character at position 124 (decimal). The pipe character is depicted as either a solid vertical bar or a vertical bar with a break in the middle (broken bar). The character is usually depicted as a broken bar on IBM PC keyboards to distinguish it from other characters.
See pipe for other uses of the word.
