Both in simulation and in debug, the conversion of the `char` is correct only at the beginning, then when changing the `char` it goes to `00h`. **Is this a bug?** ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/5/586cc4a7eeb6e8aae83820f095fe66c82cb5e472.png) ---

It does seem to be a problem. Having a letter on startup produces correct output. Changing to any letter produces “00h” output. Changing to number outputs correct number. Changing back to character outputs 00h again. ---

That’s right, thanks for taking the time to check it out. ---
