| Migrating from IBM Informix 4gl to Genero BDL / 4GL programming topics | |
Starting with IBM® Informix® 4GL version 7.50, I4GL functions can be deployed as Web Services. The published functions can be subscribed from programs that run on a Web client in another programming language.
Web Services support was introduced in Genero Business Development Language before I4GL 7.50 was released. Each implementation is quite different, but the basic principles are the same: publishing 4gl functions as Web Services, by handling WS requests and supporting easy input and output parameter conversions between WS data formats and 4gl program variables.
