Conversational Monitor System
The Conversational Monitor System (CMS) is the end user - interface and programming interface from z / VM . The CMS was designed as an operating system for virtual machines provided by the Control Program (CP) and created with it, so that the combination CP / CMS was created.
The CMS was not designed as a multi-user system or for multi-process operation . It was originally called Cambridge Monitor System because it in Cambridge Scientific Center of IBM in Cambridge (Massachusetts) was created.
The user interface is based on the IBM 3270 and, when operated using a modern keyboard or laptop, requires a few special keys without the appropriate labeling.
It is mainly used for software development; programming languages such as Fortran , PL / I or APL are available for this. Likewise the batch languages EXEC and REXX , as well as the editor XEDIT . It is also the working environment for administrators of the z / VM guest systems z / OS and z / VSE .
