Hey Guys,

I've noticed that arrays used with split() (from the example given on the reference for split()) appear to be dynamic and require no explicit size initilialisation. That's pretty handy! The nums array below is an example.

1. int[] nums;      // array to store numbers
2. String numbers = "8 67 5 309";
3. nums = int(split(numbers, ' '));

I find this interesting because the reference page on arrays doesn't list this sort of array initialisation, this makes it a bit tricky to figure out the syntax for this case, so I ran into problems using it. I'm trying to create a similar dynamic array that stores the line numbers of certain entries of a text file stored in String lines[]. Each line is of the format '1) 5,10,12,5,0' with changing variables. The first number is the line number.

1. int pen_down_lines[];      // array to store data
   
2. int k = 0;                        // index of the array
3. 
   
4. 
   
5. for (int i = 0; i<lines.length; i++){                       // for each line
   
6.     String temp[] = split(lines[i], ") ");                  // split original string into line numbers and data
7.     nums = float(split(temp[1], ", "));                   // parse data with comma operator
8. 
   
9.     if (nums[4]==0){                            // if a 'pen down' command is located
10.       print(int(temp[0]) + ") ");                // print the line number
11. 
    
12.       int h = int(temp[0]);                      // extract the line number
    
13.       pen_down_lines[k] = h;                // store the line number in an array
    
14.       k++;                                          // increment the index
    
15.     }
16.   }
