Auto Assembler aobScan(SymbolName, AOBString)

Scans all the memory 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]
