Creating variables

[Eric Chatonet]

To be frank, I don't understand:
Below is your code snippet simplified.
What it does?
It stores a variable into a custom property: so far so good ;-)
But what more?
Please, enlighten me :-)

on mouseUp
    ask "Name of pseudo variable:" with "anExample"
    if it is empty then exit mouseUp
    put it into varName
    ask "value of variable" && varName
    if it is empty then exit mouseUp
    put it into varValue
    set the myProps[varName] of me to varValue
    answer "Do you want to retrieve the value of your variable?" with  
"Cancel" or "OK"
    if it is "OK" then
       answer "This is the value of variable" && varName & ":" && the  
myProps[varName] of me
    end if
end mouseUp
