Usage

The print statement is the simplest way to display something on the screen. Each print statement produces a line of text on the screen. The following example displays two lines of text: First line! and Second line!. After printing the two lines, the cursor is positioned on the third line, ready for the next line of printed output.

│sub Main()                                │   ║First line!              ║
│    print "First line!"                   │   ║Second line!             ║
│    print "Second line!"                  │   ║█                        ║
│end sub                                   │   ║                         ║

To display multiple things on the same line, place a semicolon at the end of the statement. Then, the cursor will remain at the end of the line so that further text can be printed on the same line.

' displays "Hello world!" on a single line

print "Hello ";

print "world!"

As a shortcut, you can combine these statements into one:

' displays "Hello world!"

print "Hello "; "world!"

The print statement can display the contents of variables.

' displays "Hello, John! You are 52 years old!"

dim name = "John"

dim age = 52

print "Hello, "; name; "! You are "; age; " years old!"

When used together with the input statement, a program can have an interactive conversation with the user.
