Pansophic Systems Ltd says that around 50% of IBM 370 sites in the UK are still running under DOS/VSE. The company also claims that the annual rate of conversion to MVS is in single figures, despite the 15 years that IBM has spent trying to convince users that it’s worth the effort and expense. The US has been less resistent to IBM’s blandishments, and the number of DOS/VSE users is probably under 20%. Consequently, Pansophic is releasing a DOS/VSE version of the Telon applications generator in the UK and probably the rest of Europe, but not on the other side of the Atlantic. Pansophic UK was established in 1974, and says that Telon DOS/VSE is the first product to be developed outside the US. Although the company is based in Chicago, non US operations now constitute around 50% of revenue, and international headquarters have recently moved to Uxbridge in Middlesex. Telon is a computer-aided software engineering appli cations generator, and it designs, prototypes, generates and tests applications generated in Cobol or PL/I. Since code generated by Telon DOS/VSE can be transferred to an MVS environ ment, and it is used in 60 of the 80 applicati on generator installations in the UK MVS arena, Pansophic claims that it can help users convert to MVS more easily and cheaply. Telon DOS/VSE supports personal computer-based development, and interfaces with several front end design tools. It operates in CICS, Batch, VSAM, DL/1, and SQL/DS environments. Since Telon DOS/VSE is personal computer-based, price relates to the number of machines, but Pansophic suggests UKP100,000 to UKP150,000 for larger installations.
