This large system of Procsy macros ran plays called by the interactive operators. Without persistent variables, game state was held in the higher-numbered parameters.
Play choices were short pass, long pass, run, field goal and punt, more than PDP-9 Football written slightly earlier.
PROCSY's value depended on keeping old 7094 computers running. Eventually PROCSY was rewritten for the CDC 6500. The author used Football as his primary test case since I used just about everything PROCSY could do to make it play.
