special attention to substring method: https://www.w3schools.com/jsref/jsref_substring.asp

Definition and Usage The substring() method extracts the characters from a string, between two specified indices, and returns the new sub string.

This method extracts the characters in a string between "start" and "end", not including "end" itself.

What bugs are you noticing with the File class? And what version of ARC are you using? (latest?)

weird stuff going on, maybe is a consequence of a single bug. I'll post simple code to  demo the issue.

function PrintLines(filename) 
{
  var lineIx = 0;
  while (!File.isReadEnd(filename)) 
  {
    var line = File.readLine(filename);
    print(lineIx + " line:" + line);
  }
}


var filename="c:\\temp\\lines.txt";

var now = new Date().toLocaleString();
if (!File.exists(filename))
{
  print("file does not exist");
  File.appendStringLine(filename, now + ">>" + "First time");
}
else
{
  print("file exists");
  File.appendStringLine(filename, now + ">>" + "foo");
}

print("reset read file");
File.readReset(filename);

print("PrintLines");
PrintLines(filename);

print("add bar");
File.appendStringLine(filename, now + ">>" + "bar");

print("PrintLines");
PrintLines(filename);

first time (file does not exist)

Close ARC, Open ARC run the script:

Q: without a close and explicit open how you control reads and writes ?

File.appendStringLine

Locks the file, and you need to close ARC.

Reading from a File locks the file too so you need to close ARC.

In your answer in #16.  I think I follow but what I cant figure out is why doesn't your code download all the questions.  Why does it stop after 9.

I don't see anything in your code that says just show the first 9 questions.
