I am a beginner at Tcl but not at programming. I am active on the [MetaKit] [wikit]. My electronic home (according to recent pages) is 134.151.70.134 - my trusty (mostly) P.C. ---- I am currently implementing symbolic algebra in Tcl using the C++ classes in "'''SymbolicC++''' An Introduction to Computer Algebra Using Object-Oriented Programming" Tan Kiat Shi and Willi-Hans Steeb Springer 1998. There is also a new second edition. See also [SWIG] '''JPF'''
