Abstract: A method, system, and computer program product for optimizing recognition of presentation space data. Presentation space data is sent from a legacy host application to a workstation. A workstation application monitors arrival of multiple predetermined presentation space definitions, and invokes an appropriate target object to process each recognized presentation space of interest. Prioritization techniques are used to optimize the recognition process, whereby higher priority definitions are processed first. A time of day heuristic is defined, which influences priority of presentation space recognition according to the time of day in which specific presentation space data typically arrives at the user's workstation. Priority pools may be used to provide a desired granularity of priority. Priority may be learned dynamically by the implementation, and may be initialized explicitly (or defaulted). Priority of a definition may be demoted if an inactivity timer expires.

Abstract: A technique, system, and computer program for run-time translation of procedurally-oriented Emulator High Level Language Application Programming Interface (EHLLAPI) calls into object-based host access calls (such as those provided with IBM's Host Access Control Library or the Open Host Interface Objects under development by the IETF), without requiring changes to the workstation EHLLAPI applications. This translation, in addition to generating the appropriate method invocation, reconciles the operational differences between EHLLAPI's sequential function call model and the event-driven approach used in the object-oriented model.

Abstract: A method and apparatus for developing persistent, single implementation host access applications deployable across multiple platforms. The interaction between host and clients is accomplished directly without platform-specific server function and with data-stream, versus screen, manipulation of host information.
