					using uCalcSoftware;

var uc = new uCalc();
// Create two independent uCalc instances
var uc1 = new uCalc();
var uc2 = new uCalc();

// Define a variable 'x' in each instance with a different value
var itemX1 = uc1.DefineVariable("x = 100");
var itemX2 = uc2.DefineVariable("x = 200");

// Use the item to get its parent context and evaluate 'x * 2'
// This correctly uses uc1's context where x is 100.
Console.WriteLine($"Context 1: {itemX1.uCalc.Eval("x * 2")}");

// This correctly uses uc2's context where x is 200.
Console.WriteLine($"Context 2: {itemX2.uCalc.Eval("x * 2")}");

// Clean up the instances
uc1.Release();
uc2.Release();
