1. The program defines execution order
2. An agent executes commands in the game world

- Let players trace program execution on a specific input.

## How it works

A program solves a task by transforming specified inputs into outputs with limited instructions and memory.

## Variants

### Mechanic variants

<a id="t115-variants"></a>

- Sequences order a set of simple instructions. <a id="t115-v1"></a>
- Loops repeat actions until a stopping condition. <a id="t115-v2"></a>
- Branches choose responses from input values. <a id="t115-v3"></a>
- Memory limits require reusing stored data. <a id="t115-v4"></a>

## Design example

A robot sorts labeled parcels with one sensor and only two available memory cells.

Prototype check: Test unseen inputs so a valid program does not merely memorize the displayed tutorial example.

## Context and limits

Automation moves repeated work into a system; the player builds connections and identifies the limiting stage. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.
