. This tool could be modified to generate code of different styles, and also, to generate code in different programming languages.

The I-OOA tool has since been superseded by iUML. iUML is based on the I-OOA technology, but has been updated to support an executable subset of the Unified Modelling Language known as Executable UML

Executable UML

Executable UML, often abbreviated to xtUML or xUML, "is a single language in the UML family, designed to define the semantics of subject matters precisely." Executable UML is the evolution of the Shlaer-Mellor method to UML...
