Auto Assembler:aobScanRegion
Auto Assembler aobScanRegion(SymbolName, StartAddress, StopAddress, AOBString)
Scans a specific region memory between StartAddress and StopAddress for a specific byte pattern defined by AOBString and sets the resulting address to the symbol SymbolName.
Note: AOBString definition is composed by a list of one or several bytes optionally separated by spaces. Each byte definition has 2 variants:
- A group of 2 characters, where the first character is the high order nibble and the second is the low order nibble. Each character can be an hexadecimal digit (from '0' to 'F') or a wildcard character (interpreted as any hexadecimal value from 0 to 15)
- An unique wildcard surrounded by spaces (interpreted as any value from 0 to 255)
The wildcards are defined by any of these 3 characters: 'x', '?', or '*'. Some valid patterns:
5x 48 8D 6x 24 E0 5? 48 8D 6? 24 E0 5* 48 8D 6* 24 E0 xx 48 8D xx 24 E0 ?? 48 8D ?? 24 E0 ** 48 8D ** 24 E0 x 48 8D x 24 E0 ? 48 8D ? 24 E0 * 48 8D * 24 E0
Command Parameters[edit]

| StartAddress | string | The address to start scanning from |
| StopAddress | string | The address to stop scanning at. |
