Next: Z80 Opcodes, Previous: Z80 Floating Point, Up: Z80-Dependent
as for the Z80 supports some additional directives for compatibility with other assemblers.
These are the additional directives in as for the Z80:
db
expression
|
string
[,
expression
|
string
...]
defb
expression
|
string
[,
expression
|
string
...]
For each string the characters are copied to the object file, for
each other expression the value is stored in one byte.
A warning is issued in case of an overflow.
dw
expression
[,
expression
...]
defw
expression
[,
expression
...]
For each expression the value is stored in two bytes, ignoring
overflow.
d24
expression
[,
expression
...]
def24
expression
[,
expression
...]
For each expression the value is stored in three bytes, ignoring
overflow.
d32
expression
[,
expression
...]
def32
expression
[,
expression
...]
For each expression the value is stored in four bytes, ignoring
overflow.
ds
count
[,
value
]
defs
count
[,
value
]
Fill count bytes in the object file with value, if
value is omitted it defaults to zero.
equ
expression
symbol
defl
expression
These directives set the value of symbol to expression. If
equ is used, it is an error if symbol is already defined.
Symbols defined with equ are not protected from redefinition.
set
This is a normal instruction on Z80, and not an assembler directive.
psect
name
A synonym for See Section, no second argument should be given.
