Primavera Riak Analysis

Hi,

I'm looking for help with creating a COM file to use in place of the Macros with Primavera Risk Analysis. Please can someone provide me with a simple code listing to perform an action during each iteration through a risk model. From this I hope to be able to modify the code so that I can get it to perform the following.

I want to check the end date of a task and based on the month then add a sucssessor to one of three possible tasks. I have tried using the probabilistic branch but it does not take into account the date.
