## Main Question or Discussion Point

I have 2 variables A and B.

A can be computed from B like this

Now I would like to compute B from the above code

It can be either

or

I am not sure which way as well as the correct inverse OR operator it is that I'm seeking, I'm so confused..

A can be computed from B like this

Code:

```
Input: BOOL b, OBJECT B
A=(B<<5)
if NOT b then
A=[A OR 0xFF]
```

Code:

`Input: BOOL b, OBJECT A`

Code:

```
B=A>>5
if NOT b then
B= ?
```

Code:

```
if NOT b then
B=?
B=A>>5
```
