The dynamic assembler does not allow labels and comments. The specific line format
looks similar to:
< sp> OPERATION [OPERAND] < CR>
The first < sp> is to be compatible with structured assemblers. A space must be the
first character of each line.
Assembler Operation Codes
An operation can be either a valid 68000 instruction or a directive. The only directive
recognised by the assembler is DC.W.
The size of the affected data field may be specified by the data size code. If not explicitly
specified, a default size is taken.
BYTE
.B
8 bit
WORD
.W
16 bit (default)
LONG
.L
32 bit
Several instructions do not have or do not request a data size specification.
Format:
OP [.SIZE]
Valid operations are:
MOVE .B
move
byte
ADD
add word
NOP
no operation
Invalid operations are:
RTS.B
return from subroutine, illegal size spec.
ORG
directive not supported
Operands and Addresses
Format: < sp> [OP1[,OP2]]
The operand field follows the operation field, separated by a space. Zero, one or two op-
erands are possible depending on the instruction. The second operand is separated by a
comma as a delimiter.
In this case: OP1 is source
OP2 is destination
