 Dialog Manager Function
ISPF dialog manager provides different kinds of services to dialogs while they are running and also controls the interaction of the dialog's elements. You could think of it as an extension of the host operating system. For example, ISPF can issue requests for - panels to be displayed, or
- screens to be formatted.
It can verify, process, and store input, and it can create output. ISPF can also function as a simplified data management system for small amounts of data stored in tables. Dialog Manager also provides library access services that help you perform system utility functions on ISPF libraries or data sets. An edit recovery service helps you recover the changes you made to a data set before a system failure. The edit interface and browse interface services allow you to provide I/O to edit or browse data that is not in either a sequential or a partitioned data set (PDS). Benefits
Enables applications to easily use the display capabilities of z/OS without the requirement to write the display functions. Provides the ability to easily develop end user action dialogs. |
