## Data Definition
|
|
|
|
| Mnemonic | Syntax | Description |
|
|
|----------|--------|-------------|
|
|
| **DB** | `name: value1 [, value2, ...]` | Define bytes</br>*(byte aligned)*|
|
|
| **DH** | `name: value1 [, value2, ...]` | Define half-words</br>*(2 byte aligned)*|
|
|
| **DW** | `name: value1 [, value2, ...]` | Define words</br>*(4 byte aligned)*|
|
|
|
|
**Examples:**
|
|
|
|
```dsa
|
|
db message: "Hello World", 0, 0x20, 231
|
|
dh numbers: 1000, 2000, 3000
|
|
dw stack: 0x10000
|
|
```
|
|
|
|
**Notes:**
|
|
|
|
- All string literals are automatically *null-terminated*

## Memory Reservation
|
|
|
|
| Mnemonic | Syntax | Description |
|
|
|----------|--------|-------------|
|
|
| **RESB** | `name: size` | Reserve bytes |
|
|
| **RESH** | `name: size` | Reserve half-words |
|
|
| **RESW** | `name: size` | Reserve words |
|
|
|
|
**Examples:**
|
|
|
|
```dsa
|
|
resb buffer: 256 ; Reserve 256 bytes
|
|
resh array: 100 ; Reserve space for 100 half-words
|
|
resw heap: 1024 ; Reserve space for 1024 words
|
|
```

## Imports
|
|
|
|
| Mnemonic | Syntax | Description |
|
|
|----------|--------|-------------|
