String Array sort can not be used in build 2485.

[Yu Zhang]

void OnStart()
  {
   string a[]={"c","a","b"};
   test(a);
  }
//+------------------------------------------------------------------+
void test(string &data[])
  {
   ArraySort(data);
  }

now, it return the result:  'ArraySort' - constant cannot be modified.

But, before build 2485, string array can be sort.

Still an issue - not solved!

The documentation clearly states “Sorts the values in the first dimension of a multidimensional numeric array”. PICNIC.

I was looking for the same, and found the official solution from Metaquotes... 
I am posting here to help out the next one searching for it.

https://www.mql5.com/en/docs/standardlibrary/datastructures/carraystring/carraystringinsertsort 

This link to the documentation shows a function called InsertSort... with no documentation to .Sort, but you can see it in the example for the InsertSort on the link above.

On top of that, the entire library is appropriate for string arrays... Enjoy!

//--- example for CArrayString::InsertSort(string)
#include <Arrays\ArrayString.mqh>
//---
void OnStart()
  {
   CArrayString *array=new CArrayString;
   //---
   if(array==NULL)
     {
      printf("Object create error");
      return;
     }
   //--- add arrays elements
   //--- . . .
   //--- sort array
   array.Sort();
   //--- insert element
   if(!array.InsertSort("ABC"))
     {
      printf("Insert error");
      delete array;
      return;
     }
   //--- delete array
   delete array;
  }

That's really handy to know - thanks

Unfortunately I spent time writing one before I read this!! LOL
