TALK2C: a tool for automatic migration

The IT infrastructure of today´s organizations is often populated with yesterday´s legacy systems which trace an evolutionary path, with ad hoc changes and enhancements spread over a period of time and an inadequate change history. The inherent knowledge is normally contained in the code, which is written in an arcane language, understandable to a few and hard to maintain. Automated translation provides a convenient solution to these issues when maintaining the existing system is the main issue and the source and target languages share the same programming paradigms. TALK2C was developed to automate the conversion of code from SabreTalk to C language. SabreTalk a derivative of PL/1, runs on an earlier version of the TPF (Transaction Processing Facility) system.
