Here's my list of how to create and access things in Small Basic. I use this when I need to jog my memory but don't want to search through the Introducing Small Basic guide.

Create

Array: 

myArray[1] = "myString"
TextWindow.WriteLine(Array.GetItemCount(myArray))

Directory:

File.CreateDirectory("C:\temp\myTempDir")

Ellipse:

GraphicsWindow.DrawEllipse(10, 15, 75, 25)
' Or...
myEllipse = Shapes.AddEllipse(100, 50)

Flickr image:

GraphicsWindow.DrawImage(Flickr.GetPictureOfMoment(), 0, 0)

For statement:

For i = 1 To 10
    TextWindow.WriteLine(i)
EndFor

If/Then statement:

If Clock.Year = 2010 Then
    TextWindow.WriteLine("2010")
Else
    TextWindow.WriteLine("Not 2010")  
EndIf 

Image:

myImage = Shapes.AddImage(ImageList.LoadImage("http://www.microsoft.com/about/images/home_blue.jpg"))

Label:

Goto myLabel
myLabel:
    TextWindow.WriteLine("Hello, World!")

Line:

GraphicsWindow.DrawLine(10, 20, 100, 50)
' Or...
myLine = Shapes.AddLine(15, 20, 40, 65) 

Rectangle:

GraphicsWindow.DrawRectangle(5, 15, 80, 35)
' Or...
 
myRectangle = Shapes.AddRectangle(50, 35)

Shape:

myEllipse = Shapes.AddEllipse(100, 50)

Stack:

Stack.PushValue("myStack", "myValue")
TextWindow.WriteLine(Stack.PopValue("myStack"))

Subroutine:

mySub()
Sub mySub
    TextWindow.WriteLine("Hello, World!")
EndSub

Triangle:

GraphicsWindow.DrawTriangle(10, 15, 50, 100, 75, 25)
' Or...
 
myTriangle = Shapes.AddTriangle(30, 10, 100, 75, 145, 35)

Access

Clock functions: 

TextWindow.WriteLine(Clock.Date)

Desktop:

TextWindow.WriteLine(Desktop.Height)

Dictionary:

TextWindow.WriteLine(Dictionary.GetDefinition("banana"))

File functions:

TextWindow.WriteLine(File.GetTemporaryFilePath())

Graphics window:

GraphicsWindow.DrawBoundText(20, 10, 80, "Hello, World!")

Image:

GraphicsWindow.DrawImage(ImageList.LoadImage("http://www.microsoft.com/about/images/home_blue.jpg"), 0, 0)

Image list:

TextWindow.WriteLine(ImageList.GetHeightOfImage(ImageList.LoadImage("http://www.microsoft.com/about/images/home_blue.jpg")))

Math functions:

TextWindow.WriteLine(Math.SquareRoot(25))

Mouse:

GraphicsWindow.MouseDown = OnMouseDown
Sub OnMouseDown
    If Mouse.IsLeftButtonDown Then
        GraphicsWindow.Title = "Left button pressed"
    Else  
        GraphicsWindow.Title = "Left button not pressed"
    EndIf 
EndSub

Network functions:

TextWindow.WriteLine(Network.GetWebPageContents("http://www.microsoft.com/"))

Program functions:

TextWindow.WriteLine(Program.Directory)

Sound functions:

Sound.PlayBellRingAndWait()

Stack:

Stack.PushValue("myStack", "myValue")
TextWindow.WriteLine(Stack.PopValue("myStack"))

Text functions:

TextWindow.WriteLine(Text.GetLength("myText"))

Text window:

TextWindow.WriteLine("Hello, World!")

Timer:

Timer.Tick = OnTick
Timer.Interval = 5000
Sub OnTick
    TextWindow.WriteLine(Clock.Time)  
EndSub

Turtle:

Turtle.Move(100)
