Updated Nov 21, 2025
Architecture
Tiny BASIC interpreter runs on a microcontroller or small computer
Programs are stored in RAM or simple persistent storage
Input/output handled via console, serial, or simple hardware interfaces
Single-threaded, sequential execution model
No underlying OS or multitasking
Rendering Model
Interpreter reads and executes line-numbered code
Variables stored in RAM
PRINT outputs to console or serial terminal
INPUT reads from user or hardware
Sequential execution, no multitasking
Architectural Patterns
Single-threaded interpreter
Sequential execution model
Memory-constrained variable storage

Design Principles
Minimal memory footprint
Simplicity and readability
Integer arithmetic for performance
Line-numbered sequential execution
Portability across tiny hardware
Scalability Guide
Keep programs small and modular
Use subroutines via GOSUB/RETURN
Limit variable usage to available memory
Break complex logic into smaller line-numbered sections
Combine with hardware timers or GPIO as needed
Migration Guide
Port small BASIC programs from other interpreters
Adjust to line-numbered sequential flow
Use integer arithmetic where floats unsupported
Adapt I/O for console or minimal hardware
Verify memory usage on constrained platforms
