C# "scanf" with Custom Console

My program is a Windows Form Application in C#.

I have an interpreter/compiler IDE w/c basically runs a custom Language through a customized console window.

When interpreting input lines like "scanf", how do pause the interpreting while the user doesn't press enter?

Sample custom code to parse:

1     VAR x AS INT
2     START
3        INPUT: x
4        OUTPUT: x
5     STOP

For example, in those lines, when my program processes line 3, it doesn't process the other lines until the user inputs something and presses enter.

Pseudo-Snippet for line by line parsing:

foreach (string line in inputCode)
{
   LineType lineType = line.getType();

   if(lineType.InputStatement)
   {
   //wait for input here
   }
   else if(lineType.OutputStatement)
   {
   //analyze output code here
   }
   else if(lineType.AssignmentStatement)
   {
   //do Evaluation here
   }
}

Console.Readline or Console.ReadKey will allow you to read input from the console simillar to scanf.

You should make each method raise an event to fire the next line.
The INPUT method should fire that event after the user presses enter.
