Ensure REXXMAST is loaded (execute REXXMAST to start it manually)
When ASp is loaded, Select Run Arexx from the Project menu.
Select POKEr.asprx in the file requester. It will probably be in S:Rexx, but may vary on how you have set up ASp. Do a search for this file if you are unsure.
In the box similar to the one shown above, enter the ADDRESS then a comma, then the VALUE and press RETURN
Repeat as many times as needed.
Click the RUN button on the ASp interface to start the game.
