EXECUTE
The Code Forge
Programming Languages, Syntax & Software Creation
Central Doctrine
An algorithm describes what must be done. Programming gives that algorithm a precise language that a computer can execute. This realm explores how abstract human ideas are translated into source code—structuring logic through variables, loops, and functions—and finally compiled into machine operations.

The Bridge to Structure
REALM 06 taught program structure:
VARS → LOOPS → FUNCTIONS → EXECUTION
↓
REALM 07 asks:
How should DATA be organized inside?
- Code provides the actions.
- But actions require organized memory to process efficiently.
- Next, we explore how data is structurally arranged in memory.
