The proposed solution addresses one of the main challenges faced by organizations maintaining critical systems developed in the 1980s and 1990s: the need for modernization without operational disruption. CodeCraft IDE offers a complete ecosystem comprising a 4GL interpreter, a bidirectional 4GL↔Python converter, a modern web IDE, and an enterprise toolkit for large-scale migration. Results demonstrate that the tool can execute 4GL code, convert entire projects while preserving original code semantics, and provide detailed migration readiness reports. With over 470 automated tests and bilingual documentation, the project represen
