8.27.3 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
