  3. || MODULE NAME:  EndWait                                              ||
  4. || DEPENDENCIES: System                                               ||
  5. || LAST MOD ON:  9006.04                                              ||
  6. || PROGRAMMER:   Naoto Kimura                                         ||
  7. ||                                                                    ||
  8. ||     This unit was developed because of the "feature" of the Turbo  ||
  9. || Pascal (version 5.0) integrated environment which causes it to     ||
  10. || immediately flip back to the edit screen after the program exits.  ||
  11. || Hopefully, this will simplify the usage of Turbo Pascal for the    ||
  12. || Comp 182 students for which this unit was developed.               ||

  20. ||               Original release                                     ||
  21. || 9004.08       Naoto Kimura                                         ||
  22. ||               Rewrote parts in assembler to reduce size of TPU.    ||
  23. || 9004.10       Naoto Kimura                                         ||
  24. ||               Rewrote same parts as inline statements to eliminate ||
  25. ||               separate assembler file to generate OBJ.             ||
  26. || 9006.04       Naoto Kimura                                         ||
  27. ||               Made minor fix to make code smaller and better.      ||
