Here is a simple little program. It does not realy do much, but if you look at the code I think it does basicaly what you want. Use the left mouse button to select a new random type.
If this is not what you want, just say so!
Type whatever Field number End Type For whatevers=0 To 100 w.whatever=New whatever w\number=whatevers Next While Not KeyDown(1) Delay 1 If MouseHit(1) pick=Rand(0,100) EndIf For w.whatever=Each whatever If w\number=pick Print w\number EndIf Next Wend
