HELP ASAP!!!

I have an Arduino Micro, 2 XBee S1's, one FSR sensor. I am using MatLab and Arduino 1.0.5 for coding. I want to be able to get the pressure sensor values transmitted wireless, using the XBees, to the PC. So it would go as follows: Pressure Sensor >> Arduino Micro>> Xbee S1 >> XBee S1 >> PC. This is my coding for the arduino program 1.0.5 :

//initializing variables
int mode =-1;

//define where the pins are connected
int value;

void setup()
{
  //initialize serial communications at 9600 bps
  Serial.begin(9600);
  //check serial communication - acknowledgement routine
  Serial.println('a');
  char a = 'b';
  while (a!='a')
  {
    //wait for a specific character from the pc
    a=Serial.read();
  }
}

void loop()
{
  if (Serial.available()>0) //check if any data has been sent by the PC
  {
    mode=Serial.read();  //check if there is a request for any data
    switch(mode)  //used to set different modes for various operations. F is used to read values
    {
      case 'F':  //Force sensor
      value= analogRead(A0);  //sensor connected to A0
      Serial.println(value);  //send value over Serial
      break;
    }
  }
}

And now I want to make some type of coding in MatLab, to create some type of handshake between all the devices and both programs. I need someone to help me on this! smiley-confuse smiley-confuse

Who is ASAP and why does he need help?

If you seriously need help quickly why not choose a sensible and useful title?

And don't use upper-case - shouting is bad manners.
