Count characters from end of a string to front

Hi
You can use this code:

function Test()
{
  var str = "Hello"
  var startPos = aqString.Find(str, "e");
  var result = aqString.GetLength(str) - startPos - 1;
  Log.Message(result)
}

or (for JavaScript)

function Test()
{
  var str = "Hello"
  var patt = new RegExp('e' + '.*$');
  var result = aqString.GetLength(str.match(patt)) - 1
  Log.Message(result);
}

This will work if your word has only one "e" in or you want to find everything following the first "e"

e.g. "Here we go"

would return "re we go"

if you want to find the last one though, you need a 

aqString.FindLast("Here we go", "e", true);  which should return " go"

With javescript the regex searches from the end ($) 

For some characters:

function Test()
{
  var results = getCount("ere we ge", "e")
  for(result of results) 
    Log.Message(result)
}

function getCount(str, char)
{
  var startIndex = 0;
  var result =[];
  var startPos = aqString.Find(str, char, startIndex);
  while(startPos != -1)
  {
    result.push(aqString.GetLength(str) - startPos - 1);
    startIndex = startPos + 1;
    startPos = aqString.Find(str, char, startIndex);
  }
  return result;
}
