The .DWORD
pseudo-operation reserves storage and initializes it to the given
value.
Syntax |
 |
.DWORD [ init_value [,
init_value] ...]
Parameters |
|
- init_value
An absolute expression, a decimal, octal, or hexadecimal
number, or a sequence of ASCII characters surrounded by quotation
marks. If you omit the initializing value, the Assembler initializes
the area to zero.
Discussion |
|
The .DWORD
pseudo-operation requests 64 bits of storage. If the location counter
is not properly aligned on a boundary for a data item of that size,
the Assembler advances the location counter to the next multiple
of that item's size before reserving the area.
When you label the pseudo-operation, the label refers to the
first byte of the storage area. Operands separated by commas initialize
successive units of storage.
Example |
|
The first pseudo-operation advances the current subspace's
location counter to a double word boundary, allocates a double word
of storage labeled F
and initializes that double word to minus 64 (2s complement). The
second pseudo-operation initializes a double word of storage to
the hexadecimal number 6effffff12345678.
F .DWORD 64
.DWORD 0X6effffff12345678 |
