A quoted literal is a string of characters enclosed in double
    quotes (" ").  Use the following guidelines when specifying
    characters in a quoted literal:

    o  Any character except null, carriage return, and form feed can
       appear within the string.

    o  To include a double quote or backslash in a string, you must
       precede it with a backslash (\).

    o  To specify an arbitrary character, you can specify "\xhh",
       where each h represents a single hexadecimal digit. For
       example:

       "AB\\CD\"EF\x47"

       This string contains the following characters:

       AB\CD"EFG

    Also note that the assembler does not convert the case of
    alphabetic characters within a quoted literal.

    Quoted literals can be continued over several lines. Use the
    hyphen (-)  as the line continuation character and delimit the
    string with double quotes. For example:

    .ASCII "Strings are delimited with double quotes."
    .ASCII "The backslash is an escape character."
    .ASCII "Strings can be continued onto multiple lines -
    just as any other line."
    .ASCII "Use two backslashes (\\) to represent -
    the back-slash itself."
    .ASCII "Hexidecimal escape sequences use -
    lower or upper X: \x00 or \X00"
    .ASCII "Precede a double quote with a backslash (\") -
    to embed the quote."
