@cindex Epiphany line comment character
|
||
|
|
The presence of a @samp{;} on a line indicates the start
|
||
|
|
of a comment that extends to the end of the current line.
|
||
|
|
|
||
|
|
If a @samp{#} appears as the first character of a line then the whole
|
||
|
|
line is treated as a comment, but in this case the line could also be
|
||
|
|
a logical line number directive (@pxref{Comments}) or a preprocessor
|
||
|
|
control command (@pxref{Preprocessing}).

line.
