-## Size
+<Code:Basic>
-Typical Tiny BASIC interpreters:
-* **1–4 KB total**
-* Some famous versions were under **2 KB**
-* A few extreme versions fit in **less than 1 KB**
-This was achieved through:
-* Hand-written assembly
-* Tokenization
-* Shared code paths
-* Aggressive simplification of syntax

-Each one differed slightly, but all followed the “tiny, usable, interactive” idea.

-## Why Tiny BASIC matters
-Tiny BASIC is important because it:
-* Made programming accessible on the *cheapest possible hardware*
-* Helped bootstrap the early microcomputer software ecosystem
-* Demonstrated how interpreters could be **designed under extreme constraints**
-* Influenced later minimal languages and embedded scripting systems
-It’s often cited as an early example of **open, shared language design**, since many implementations were published openly in magazines.

-## In one sentence
-> **Tiny BASIC is a deliberately minimal BASIC interpreter, typically fitting in a few kilobytes, designed to make interactive programming possible on the earliest and most constrained microcomputers.**
-If you’d like, I can:
-* Show a **formal Tiny BASIC grammar**
-* Compare Tiny BASIC vs Microsoft BASIC
-* Explain how a Tiny BASIC interpreter works internally
-* Show how to write your own Tiny BASIC in C or assembly
