when i started to make [this](http://kll.engineering-news.org/kllfusion01/downloads/RPI_processing34_418.jpg)  
i used the

```auto
import javax.swing.JOptionPane;

// for button menu ask setpoint input
// _________________________________________________________________ askI call: A = askI("A",A);
int askI(String ask, int I) {
  String r = JOptionPane.showInputDialog(null, "new Setpoint for "+ask+" (now "+I+" )", "Input (INT)", JOptionPane.QUESTION_MESSAGE);
  if (r == null ) { 
    print(" NULL "); 
    r = str(I);
  } // handle CANCEL
  try { 
    I = Integer.parseInt(r);
  } 
  catch(NumberFormatException e) { 
    println("you did not enter a int number!");
  }
  println("new "+ask, I);
  return I;
}

// _________________________________________________________________ askF call: A = askF("A",A);
float askF(String ask, float F) {
  String r = JOptionPane.showInputDialog(null, "new Setpoint for "+ask+" (now "+F+" )", "Input (FLOAT)", JOptionPane.QUESTION_MESSAGE);
  if (r == null ) { 
    print(" NULL "); 
    r = str(F);
  } // handle CANCEL
  try { 
    F = Float.parseFloat(r);
  } 
  catch(NumberFormatException e) { 
    println("you did not enter a int or float number!");
  }
  println("new "+ask, F);
  return F;
}

int a = 0;
float b = PI;
void setup() {
  a = askI("input a ", a);
  b = askF("input b ", b);
  println("a "+a+" b "+b);
}
void draw() {
}

```
