Special Characters

#’ is the line comment character. If a ‘#’ appears as the first character of a line, the whole line is treated as a comment, but in this case the line can also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).

A semicolon (‘;’) can be used to start a comment that extends from wherever the character appears on the line up to the end of the line.

The ‘|’ character can be used to separate statements on the same line.
