ISPF And XEDIT Display System

       Handling of ISPF and XEDIT panel displays within
interactive applications is a repetitive and time-consuming
programming activity.  A facility was needed to provide a high degree
of code reuse for interactive applications and make the development
of such systems more productive.

      The ISPF and XEDIT Display (IXD) Handler provides a set of
tools to aid in the management of interactive dialogs in VM
applications.  IXD provides a tool enabling rapid development of
interactive applications  with a minimum of new coding.  IXD
encourages isolation of application changes to panels and data files,
making the application more flexible and more easily adapted or
extended.  Details of panel displays for the ISPF environment are
hidden from the developer and a large amount of panel handling code
can be reused across applications.

      IXD provides facilities supporting the creation of menus,
"safe" invocation of ISPF, display of text,  data entry, and help
panels, and generic input/output facilities. Dialogs are defined via
display control files.  IXD handles all display processing for the
panels and provides for simple or complex chaining from panel to
panel.  Pre and post exits may be invoked for each panel for special
initialization or validation processing.  IXD supports use of ISPF
file tailoring files for creation of data files, including the use of
different data for- mats based on the interactive users reactions....
