Line comments are introduced by the | character appearing anywhere on a line, unless the --bitwise-or command-line option has been specified.
An asterisk (*) as the first character on a line marks the start of a line comment as well.
A hash character (#) as the first character on a line also marks the start of a line comment, but in this case it could also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing). If the hash character appears elsewhere on a line it is used to introduce an immediate value. (This is for compatibility with Suns assembler).
Multiple statements on the same line can appear if they are separated by the ; character.
