Next: , Up: AVR Syntax   [Contents][Index] Special Characters

The presence of a ; anywhere on a line indicates the start of a comment that extends to the end of that line.

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).

The $ character can be used instead of a newline to separate statements. Note: the -mno-dollar-line-separator option disables this behaviour.
