- Messaging
  - Typically Midas commands communicate by sending Messages to one another.
  - Historically messages have three main parts:
    Name
      The name of the message.
    Info
      A single integer containing "information."
      This is a historical artifact; newer applications make less use of this field.
    Data
      In NeXtMidas this is an Object (typically a Table).
      In X-Midas this can either be a structured set of parameters (called a "configured message") or a semi-free-form set of values (called an "unconfigured message").
