Chainer

Introduction

Nikhil had the excellent idea of running a compendium of games from a single program. Compile the three programs (Nikhil's GoalQuest and MazePlus and Neil's Roller) and put the full pathname of each executable into the code. We put them all in the folder D:\games to make this code work for us.

The Program

program Chainer;

Remarks

Could you write a program to run your games in succession?
