A semicolon (‘;’) appearing anywhere on a line starts a comment that extends to the end of that line.
If a ‘#’ appears as the first character of a line then the whole line is treated as a comment, but it can also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).
Multiple statements can appear on the same line provided that they are separated by the ‘{’ character.
The character ‘$’ in jump instructions indicates current location and implemented only for TI syntax compatibility.
