Here's the problem: a symbol fname contains the name of a Mathematica object, e.g.: fname = "myf" The question is how to determine the context of the object named by fname (in our case, the context of myf). The question comes down to how to torture fname in order to supply the result as argument to Context. I've tried all sorts of combinations of SymbolName, ToExpression, and ToString, but Mathematica keeps complaining -- error message is Context::ssle : Symbol, string, or HoldPattern[symbol] expected at position 1 in Context[...]. There's something I'm missing. (Like many such things, this one is trivial to do in APL or J; I'm just not "getting it" how to do the same thing in Mathematica.) -- Murray Eisenberg Internet: murray at math.umass.edu Mathematics & Statistics Dept.
