I am employed by Case Western Reserve University [http://www.cwru.edu/] and work at the Cleveland Functional Electrical Stimulation Center [http://www.fesc.org/], a biomedical engineering R&D consortium. I use Tcl for internal projects, including PC-based user interface software for embedded controllers and for testing of said embedded controllers. Did an early (and obscure!) port of Tcl 2.1 to MS-DOS sometime before 1992. Personal homepage is at http://kg8ih.cit.cwru.edu/sct/ Can be reached by e-mail at mailto:sct@po.cwru.edu
