ISPF enables you to edit host data on a workstation, and workstation data on the host. ISPF calls this function distributed editing.

The ISPF Workstation Tool Integration dialog, or tool integrator, is a workstation customization tool that enables any workstation application to use data from an MVS™ host system. After setting up the tool integrator, your workstation-installed applications can interact with the ISPF View and Edit functions and services. Data flow goes both ways with the tool integrator connection. You can work with workstation files on the host or with host files on the workstation.

For more information about distributed editing, refer to the z/OS ISPF User's Guide Vol II and the z/OS ISPF Services Guide.
