name

Introduction

This program asks for the user's name, and then greets the user. It demonstrates the use of read-line to read input, and introduces variables.

Discussion

Input

The program uses the procedure read-line to read input. As you will have guessed, this procedure reads one line of input. The line is returned without the terminating newline.

Variables

This program uses a variable called name. The expression (define name (read-line)) defines the variable and initializes it to the value returned by read-line. (This also shows how to nest expressions.) Using the variable is accomplished simply by writing the name of the variable.
