Setting Variables to Full-Code Segments

[cloneryan02]

So i've been trying to refine my code, and I wanted to do this,

set recipientName to "Me"
set recipientAddress to "cloneryan61002@gmail.com"
set theSubject to "Type your subject here!"
set theContent to "Type your message content here!"

(*This will send the message.*)
set codeSet2 to (tell application "Mail"

        ##Create the message
        set theMessage to make new outgoing message with properties {subject:theSubject, content:theContent, visible:true}

        ##Set a recipient
        tell theMessage
                make new to recipient with properties {name:recipientName, address:recipientAddress}

                ##Send the Message
                send

        end tell
end tell)

I just typed up this code, but I can't the chunk of code into a variable (codeSet1)

I want it in a variable so it's easier to manipulate, so if I change one thing, it basically changes it once, instead of the twenty times it takes to retype everything.

Does anyone know how to turn this code into a variable?
