sval

Assemble a string. 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 @begingroup
