9.57.3 Assembler Directives for the Z8000

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).

segm

.z8001

Generate code for the segmented Z8001.

unsegm

.z8002

Generate code for the unsegmented Z8002.

name

Synonym for .file

global

Synonym for .global

wval

Synonym for .word

lval

Synonym for .long

bval

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'
