Contents|Index|Previous|Next Comments There are two ways of rendering comments to as. In both cases the comment is equivalent to one space. Anything from /* through the next */ is a comment, as in the following statement. /*    The only way to include a newline (’\n’) in a comment    is to use this sort of comment.  */ This means you may not nest the following types of comments. /* This sort of comment does not nest. */ Anything from the line comment character to the next newline is considered a comment and is ignored. The line comment character is ‘#’ on the Vax; ‘#’ on the i960; ‘!’ on the SPARC; ‘|’ on the 680x0; ‘;’ for the AMD 29K family; ‘;’ for the H8/300 family; ‘!’ for the H8/500 family; ‘;’ for the HPPA; ‘!’ for the Hitachi SH; ‘!’ for the Z8000; see Machine dependent features for specific architectures. On some machines there are two different line comment characters. One character only begins a comment if it is the first non-whitespace character on a line, while the other always begins a comment. To be compatible with past assemblers, lines that begin with ‘#’ have a special interpretation. Following the ‘#’ should be an absolute expression (see Expressions): the logical line number of the next line. Then a string (see Strings) is allowed: if present, it is a new logical file name. The rest of the line, if any, should be whitespace. If the first non-whitespace characters on the line are not numeric, the line is ignored. (Just like a comment.)                     # This is an ordinary comment.  # 42-6 "new_file_name" # New logical file name                      # This is logical line # 36. This feature is deprecated, and may disappear from future versions of as. Top|Contents|Index|Previous|Next
