I need a function, let's call it Store, that takes two strings as arguments -- the NAMES of two variables the second ov which variables currently has some value -- and that causes the value in that variable to be assigned to the symbol. (I don't care what the result returned by the function is; Null will do just fine.) For example: temp = {1, 2, 3}; Store["x", "temp"] After evaluating those expressions, the list {1,2,3} of numbers would be assigned to the variable x. I tried the "obvious" thing: Store[newvar_String, datavar_String] := (newvar<>"="<>datavar; Null) but that does not work. I've tried various alternatives, such as inserting "Evaluate@"<> just before datavar in the above definition, but that doesn't do it, either. More generally, I'd like Store to be able to accept as second argument the string representation of any expression, where such expression, when evaluated, give the value to be assigned to newvar. Evidently I'm having a lot of trouble juggling symbols, names of symbols, values, etc., in Mathematica (3.0). Can you help me? -- Murray Eisenberg Internet: murray at math.umass.edu Mathematics & Statistics Dept.
