In this paper we describe a program restructuring tool currently  
under development.
The tool is constructed using program transformations executed by  
the TAMPR program transformation system.
We discuss the knowledge embodied in the transformations and how  
they restructure an example COBOL program developed in the  
mid-1970s.
While the tool needs to be extended further to produce a robust  
commercial product, early use for restructuring COBOL programs  
demonstrates the power and flexibility of this transformational  
approach.
