The capability was very limited. Basically you could program a looping series of commands for newly manufactured units. "Go to this waypoint #1, then waypoint #2, then this final waypoint, then go back to the beginning and start again." And IIRC you toggle a switch to select whether the units should strictly obey the commands or stop to engage in battle along the way. Typically this is used to set a destination for new units, so they assemble automatically. But because you could set the commands to loop, and because you could authorize them to auto-engage (using the built-in AI to track and follow targets they run into), you could hack it to have the new units do routine patrols without further player action. This definitely doesn't "solve" gameplay. It just gives the player access to the game's built-in AI for their own purposes. Of course it's much more useful playing against the computer than other players.
