ScreenJet Limited is a legacy-system migration tooling vendor based in Gloucester, UK, with a very narrow focus: migrating VPlus screens and the Transact language after HP/HPe3000 retirement. Its products are not general-purpose development platforms; they are designed to help enterprises still running core applications on HPe3000, MPE/iX, VPlus, and Transact reduce migration risk.
For VPlus, ScreenJet offers the EZV VPlus conversion toolkit, which extracts proprietary screen information from HPe3000 VPlus Formsfile and generates open, standards-compliant, readable XML screen definitions. EZV Designer serves as a Windows-based replacement for Formspec to maintain these definitions. More importantly, its replacement VPlus API allows applications to retain their original VPlus calls while mapping them at runtime to the new XML screens, reducing code changes and user retraining.
For Transact, TransAction provides a compiler, runtime, and Transact Function Library, enabling original Transact source code to be migrated and executed on platforms such as HP-UX, Linux, and MPE/iX. The older T2C Transact to COBOL approach has been superseded.
The official website does not publish pricing. It only states that migration-appropriate pricing is provided based on the number of programs and server scale, so users need to contact sales or migration partners. In terms of integration, it can work with MPE/iX environment support products such as AMXW, Transport, Intrins/iX, and MPUX, and it also supports Dictionary data migration to Eloquence or other databases.
Its strengths are a deep understanding of the HPe3000 ecosystem, an emphasis on automated conversion, phased testing, preserving the terminal experience, and minimizing code changesβmaking it suitable for high-risk legacy migrations.
The drawbacks are also clear: the website copyright appears to stop at 2013, and there is little information about versions, downloads, trials, technical manuals, case-study details, or maintenance activity. There is also no information on modern APIs/SDKs, CI/CD, or cloud integrations.
It is suitable for enterprises, migration firms, VARs, and consultants still working with HP3000/VPlus/Transact. It is not a fit for typical web, cloud-native, or mobile development teams. The source material does not provide information on access from China or payment methods, so these should be treated as unknown. For teams in China needing similar capabilities, it would usually also make sense to compare the Micro Focus/ACUCOBOL-GT ecosystem, Eloquence, and custom rewrite solutions from migration consultancies.
