Synopsis
Official Name: XorA
BCALL Address: 80BD
Calculates the exlusive OR (XOR) of the value in register A with itself and puts the result back in A.
Inputs
- A = Number to be XOR'd with itself.
Outputs
- A = 0
- Flags: Same as for the XOR A instruction.
Destroys
- None.
Comments
This B_CALL is a complete waste of time.
Example
This B_CALL pretty much consists entirely of
xor a ret
