Below is a part of my code :

Serial.write(‘A’);

// Print float data  
for (int i=0; i\<4; i++){  
Serial.write(myValue1.bytes[i]);  
delay(10);  
}  
// Print terminator  
Serial.print(’\n’);

3 value have been sent to serial, but I just want to receive "Serial.write(myValue1.bytes[i]) " value in processing;

it means that I need to define a header and terminator in processing;

help me for that:)
