Hi everyone,

I'm new at processing, and as I was looking through a really cool sample script (see below), and I had  a quick question. Basically, this script writes 20 lines of serial output into a file, and then it stops.

My question:  how I can I do so that the script basically loops continuously after it closes the file (i.e.: it writes a file with 20 lines, and then starts again by creating a new file with new 20 lines, etc etc), as opposed of just exiting the program?

I'm sure it is simple, but I can't figure out exactly the syntax of how to do it... Any suggestions would be suuuper helpful!

Thanks!!

1. import processing.serial.*;
   PrintWriter output;
   Serial myPort;
   String myData = null;
   String[] Data = new String[5000];
   int n = 0;
   int m = 0;
   
   void setup() {
     println(Serial.list());
     String portName = Serial.list()[0];
     // change [0] for the Arduino serial port
     myPort = new Serial(this, "COM3", 57600);
     myPort.bufferUntil('\n'); // SerialEvent for new line
     myPort.clear();
     String Name = "Data_"+str(month())+"-"+str(day())+"-"+str(year())
       +"_"+str(hour())+"."+str(minute())+".txt";
     // Create file to save the captured data
     output = createWriter(Name);
   }
   
   void draw() {
     while ( myPort.available () > 0 ) {
       myData = myPort.readStringUntil('\n');
       if ( myData != null ) {
         Data[n] = myData;
         n++;
       }
     }
     while (m < n) {
       if ( Data[m] != null) {
         output.print(Data[m]);
         m++;
       
         output.flush();
       
       }
     }
     if ( m == n ) {
       if ( m >= 20 ) { // number of data lines in 3.1 seconds.
   //      output.flush(); // Writes the remaining data to the file
         output.close(); // Finishes the file
         exit(); // Stops the program
       }
     } 
   }
