Special Characters

   The presence of a `@' on a line indicates the start of a comment
that extends to the end of the current line.  If a `#' appears as the
first character of a line, the whole line is treated as a comment.
   The `;' character can be used instead of a newline to separate
statements.
   Either `#' or `$' can be used to indicate immediate operands.
   *TODO* Explain about /data modifier on symbols.
