In this context Mainframe means IBMs MVS/XA, MVS/ESA, OS/390 and z/OS operating systems and hardware.


Special thanks to Robert Kennedy of Canada Life Assurance, Zelko Odorcic of Nova Marketing, and Jason Bridgman.

Many thanks to my MainFrame associates who all helped with suggestions and direction. IBM is of course responsible for making the hardware and OS390 available. Alana O'Donnell provided unfailing support as IBMs liason. Bruce Richardson of Videolink, Fred Downs, and Mimi Li helped with the artwork. Also thanks to Tod Sambar of Sambar Technologies who provided a model for implementation.
