Pacbase replacement- Our double approach PACStudio tool: tactical approach ◦ Keep intact Pacbase functionnalities and results − Tactical solution as it allows with minimum risk to replace IBM Pacbase by an equivalent product therefore maintaining the applications in PAC language and generating the exact same source COBOL code as Pacbase. ◦ Continuity, modernity ◦ Today’s Development/Maintenance environment under Eclipse with any local relationnal database for the support of the imported Pacbase dictionnary ◦ Local COBOL compile ◦ Possible local testing PAC 2 COBOL solution: strategic approach ◦ Full disengagement of Pacbase artefacts to the profit of iso-functionnal fully maintenable code ◦ Tool-based solution handled in project mode The 2 options can be progressively combined © 2018 TELEBIG - Tous droits réservés / All Rights Reserved. 4

Pacbase replacement Continuity and Modernization PACStudio is the answer to the request of many users of Visual. Age Pacbase, very satisfied with the historical product, but question themselves regarding its replacement, no lmater that end of 2019 now Development and maintenance compatible with Pacbase including regeneration of identical COBOL code as of Pacbase for the various target platforms (ie. z/OS, Bull GCOS, UNIX, AS/400, Windows, UNISYS, . . . ). © 2018 TELEBIG - Tous droits réservés / All Rights Reserved. 7

PACStudio : Main caracteristics « Visual Pacbase like » fully integrated Eclipse plug-in Import of Visual. Age Pacbase, from full or selective libraries into a relationnal database (commercial or Open source) Maintenance at PAC / Pacbase Macro-langage level Generators producing the same exact code as VAP, reducing to the minimum, or even eliminating Regression tests Build from our own technologies combined with Open source components, without any other third party dependency, allowing us to provide PACStudio source code to our customers © 2018 TELEBIG - Tous droits réservés / All Rights Reserved. 8

PACStudio : Local compilation PACStudio allows the local compilation of the COBOL generated code before it is shipped for final compilation to the target environment Today, associated COBOL compiler can be: ◦ ◦ ◦ Veryant is. COBOL (generates Java) Gnu. COBOL (Full Open source) Micro Focus COBOL-IT Heirloom Elastic COBOL (generates Java, directly IBM z/OS Enterprise COBOL compatible) ◦ Tmax.

PACStudio : Implementation Provision standard server/workstations infrastructure (in premises or Cloud) Installation or integration of PACStudio plug-in alone or under a Mainframe development/ off-loading environment such as the Micro Focus Enterprise Developper, Compuware Topaz , IBM RDZ, Metrixware Cobos, . . for example Installation of the local database hosting the dictionnary (Postgre. SQL, My. SQL, Oracle database, SQL Server, Tibero, …) Import of libraries using Pacbase EXLI exported data Integration with Customer preferred version control, …. tools Validation of iso-code generation of the entire customer’s portfolio Short training (one week) as there is very limited change for the developpers (Eclipse hands on required) Continuous Assistance / hot line Specific adjustements / simplifications available from our team, for instance to replace programs using PAF with native SQL Optionnal PAC 2 COBOL © 2018 TELEBIG - Tous droits réservés / All Rights Reserved. 12
