Set PATH to interpreter
Open REPL for testing
Run sample scripts
Install SRFI libraries if needed
Config Files
.rkt for Racket scripts
Module definition files
REPL initialization scripts
Makefile for batch execution
SRFI library configs
Cli Commands
racket source.rkt
scheme --script source.scm

drscheme for interactive IDE execution
Internationalization
UTF-8 support in Racket and modern Scheme
Symbols and strings can use international characters
Locale-aware number/string formatting
Text processing libraries handle multiple encodings
Macros and code remain language-independent
Accessibility
REPL facilitates interactive learning
Extensive academic tutorials
Documentation via Racket and SRFI
Community examples for learning
Debugger and trace tools available
Ui Styling
Mostly console-based
GUI via Racket GUI libraries
Visualization via external libraries
Focus is symbolic/data processing
UI handled separately from core Scheme logic
State Management
Variables in lexical scope
Closures capture environment
Global variables possible but discouraged
Macros manipulate compile-time state
Immutable data structures preferred
Data Management
Lists and pairs
Vectors and arrays
Symbols and strings
Hash tables and association lists
Streams and lazy sequences
