Hi Nicol,

Basically, yes. However, every programming language has its own unique
way of declaring and managing variables. What I'm basically saying
that every programming language has different rules how you declare
variables, but what you wrote is the basic concept. For example, in
C++ to create an integer variable you might type
int number = 1;
which would create a new integer number variable and set its value to
1. In Visual basic .NET you might do something like
Private number As Integer = 1
which would do the same thing as above, but as you can tell Visual
Basics method of declaring a new variable is much more verbose.
However, regardless of how you create the variable they all basically
work the same. To reuse one of your own examples I might asign a
message string to a variable called msg like this
msg As String = "Hello World!"
and later pass that variable to the Sapi Speak function like
sapi.Speak(msg, 0, 0)
and of course Sapi would speak "Hellow world" alloud because that is
the string of text msg holds. A more real world answer of using
variables is something like this.

Sub AddNumbers(x As Integer, y As Integer)
    result As Integer = x+y
    textbox.Text = result
End Sub

In the sample VB .NET code above I created a simple Sub that adds two
numbers together. Since we don't know what numbers are required we
have substituted them with x and y variables. Assuming this is a
calculator program the person would enter this data which would get
stored by x and y, and then the calculation can be performed. Once
calculation completes it prints it to a simple textbox on screen.
