					using uCalcSoftware;

var uc = new uCalc();
var myInstance = new uCalc();
// Define a variable and get its Item object
var v = myInstance.DefineVariable("v = 10");

// Use the item to get back to its parent uCalc instance
var parentInstance = v.uCalc;

// Perform another evaluation in the same context
Console.WriteLine(parentInstance.EvalStr("v + 5"));
