The Z8000 port of as includes additional assembler directives, for compatibility with other Z8000 assemblers. These do not begin with `.' (unlike the ordinary as directives).

sval
expects one string literal, delimited by
single quotes. It assembles each byte of the string into consecutive
addresses. You can use the escape sequence `%xx' (where
xx represents a two-digit hexadecimal number) to represent the
character whose ascii value is xx. Use this feature to
describe single quote and other characters that may not appear in string
literals as themselves. For example, the C statement `char *a = "he said \"it's 50% off\"";' is represented in Z8000 assembly language
(shown with the assembler output in hex at the left) as
