In an earlier posting, I asked how to define a function store[varname_String, dataname_String] that causes a variable to be created whose name is given by the string used as first argument and which assigns as the value of that new variable the value of the object whose name is given by the string used as the second argument. For example, x = 99; store["myx", "x"] should mean that an input myx now produces 99 as output. I found one method that works -- sort of, and sometimes -- but which I don't fully understand: store[varname_String, dataname_String] := ToExpression[StringJoin[Sequence@@{varname,"=",dataname}]] Unfortunately, I need to use such a function store inside a Module, like this: wrapper[shortname_String] := Module[{temp}, temp = ...... (* value created here *) ; store["new"<>shortname, "temp"]; .... ] and now, because temp is a local variable in the Module, the whole thing breaks down (assigning the SYMBOL temp as the value of the new... variable). A real kludge is: wrapperkludged[shortname_String] := (temp = ...... ; store["new"<>shortname, "temp"]; Remove[temp] ) but clearly that is most unpleasant (since, in my actual application, there are a whole bunch of local variables in the Module that calls the function store. So I'm still seeking a satisfactory solution! -- Murray Eisenberg Internet: murray at math.umass.edu Mathematics & Statistics Dept.
