Abstract

A generalized backwards/restart capability for the Interactive System Productivity Facility (ISPF), an IBM program product, is an apparatus capable of restarting a dialog following a system interruption and capable of reversing the sequence of panels of the dialog without loss of previously entered data. In many instances, data is entered into a data processing system via a sequence of panels of a dialog displayed on a viewing screen of the data processing system. When a system interruption occurs during the entry of data via the panels of the dialog, the apparatus enables the user to restart the dialog, without loss of previously entered data, commencing with the panel successfully displayed prior to the occurrence of the system interruption.

Generalized Backwards/Restart Capability for ISPF Dialogs

A generalized backwards/restart capability for the Interactive System Productivity Facility (ISPF), an IBM program product, is an apparatus capable of restarting a dialog following a system interruption and capable of reversing the sequence of panels of the dialog without loss of previously entered data. In many instances, data is entered into a data processing system via a sequence of panels of a dialog displayed on a viewing screen of the data processing system. When a system interruption occurs during the entry of data via the panels of the dialog, the apparatus enables the user to restart the dialog, without loss of previously entered data, commencing with the panel successfully displayed prior to the occurrence of the system interruption. Further, during the display of the sequence of panels, this apparatus enables the user to reverse the sequence of the display of the panels, that is, to proceed in a backwards direction, one panel at a time, commencing with any panel of the dialog. In the backwards direction, panels are redisplayed with the same data field values as when they were last viewed by the user. These values on the redisplayed panels may be changed and the dialog continued in a forward direction from any point while going backwards. Dialog programs using the backwards capability may be organized as any number of independent modules, calling each other in any order. There is no limit to the...
