#### Assembler Directives for the Z8000

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

`segm`
  Generates code for the segmented Z8001.
`unsegm`
  Generates code for the unsegmented Z8002.
`name`
  Synonym for `.file`
`global`
  Synonym for `.global`
`wval`
  Synonym for `.word`
`lval`
  Synonym for `.long`
`bval`
  Synonym for `.byte`
`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

                68652073    sval    'he said %22it%27s 50%25 off%22%00'
                61696420
                22697427
                73203530
                25206F66
                662200

`rsect`
  synonym for `.section`
`block`
  synonym for `.space`
`even`
  special case of `.align`; aligns output to even byte boundary.
