Abstract

The present invention relates to a structure for an on-line interactive system in which the screen has (1) common fields into which generic (or application-independent) data is entered and (2) application's fields. If there is an entry in any common field, the system ignores entries (if any) in the application's fields and an input control module performs the function represented by the common field entry. Otherwise, a process control module executes application logic. In Fig. 1, the basic interactive system structure 100 includes a Main Executive Module 102 which receives input from an input analyzer 104. The Input Analyzer 104 accepts a screen as input. The control line 22 is analyzed and code corresponding to a line 22 entry is determined.

Transaction-Centered Hierarchy for an Interactive System

The present invention relates to a structure for an on-line interactive system in which the screen has (1) common fields into which generic (or application- independent) data is entered and (2) application's fields. If there is an entry in any common field, the system ignores entries (if any) in the application's fields and an input control module performs the function represented by the common field entry. Otherwise, a process control module executes application logic. In Fig. 1, the basic interactive system structure 100 includes a Main Executive Module 102 which receives input from an input analyzer 104. The Input Analyzer 104 accepts a screen as input. The control line 22 is analyzed and code corresponding to a line 22 entry is determined. Typically, an entry on line 22 would include a NEW SCREEN function, an EXIT function, a MASTER screen function, and a HELP function. If there is an entry on line 22, the Main Executive Module 102 notifies an Input Control module 106 by communicating a "line 22, Code, ID" message thereto. The Input Control module 106 includes a look-up table, a screen generator and display, and a "help" execution and display. Based on the code and screen ID communicated to the input control module, the look- up table determines whether a NEW SCREEN or HELP execution has been requested by the user. After HELP execution, the most recent screen is re- displayed. If there is no entry in a common field, text (from application's fields) and screen ID information enter a process control module 108. The processing of the application is designed to be independent of screen format requirements, the CICS (Customer Information Control System) environment, and other features that occur as design assumptions or constraints. The process control module contains an application analyzer which, in...
