Hello guys I was recently trying to build my own OS using Cosmos , so I've finished enogh commands to fit the bill for standard user ,, my problem is the program can't work with more than one command , I want to make it like cmd and Here is sample of code `using System; using Cosmos.Compiler.Builder;
namespace CosmosBoot1
{
class Program
{
#region Cosmos Builder logic
// Most users wont touch this. This will call the Cosmos Build tool
[STAThread]
static void Main(string[] args)
{
BuildUI.Run();
}
#endregion
public static string[] outputline = { "Welcome user" };
// Main entry point of the kernel
public static void Init()
{
var xBoot = new Cosmos.Sys.Boot();
xBoot.Execute();
Console.WriteLine("Welcome to Tammaa OS ");
Console.WriteLine("Please insert a Command");
Drawconsole();
string uinput = "";
uinput = Console.ReadLine();
if (uinput == "shutdown")
{
Cosmos.Sys.Deboot.ShutDown();
}
else if (uinput == "help")
{
Console.WriteLine("shutdown \t Turn off the system");
Console.WriteLine("restart \t Restarts the system");
}
else if (uinput == "calc")
{
Console.WriteLine("Please enter the the syntax");
String operation = Console.ReadLine();
uint usernum1, usernum2;
Console.WriteLine("Please insert the 2 numbers");
usernum1 = userint(0, 100, 101);
usernum2 = userint(0, 100, 101);
if (operation == "+")
{
Console.WriteLine((usernum1 + usernum2).ToString());
Drawconsole();
}
else if (operation == "-")
{
Console.WriteLine((usernum1 - usernum2).ToString());
Drawconsole();
}
else if (operation == "*")
{
Console.WriteLine((usernum1 * usernum2).ToString());
Drawconsole();
}
else if (operation == "/")
{
Console.WriteLine((usernum1 / usernum2).ToString());
Drawconsole();
}
else
{
Console.WriteLine("An unexcepected error stoped the proccess please chack your data and try again");
Drawconsole();
}
}
else
{
Console.WriteLine("Unknown Command");
Console.WriteLine("Type help to get vaild commands,Please");
Drawconsole();
}
while (true)
;
}
public static uint userint(uint start, uint end, uint Default)
{
uint a;
String userinput = Console.ReadLine();
for (a = start; a <= end; a++)
{
if (a.ToString() == userinput)
{
return a;
}
}
return Default;
}
public static void Drawconsole()
{
Console.Clear();
Console.WriteLine("OS command here>");
}
}
}`
