Currently the function StringToArrayOfLint returns bool for success or false for not successful.

 success := StringToArrayOfLint(str, arr);

But in case that the string contains more elements as the destination array can store, shall the function return true or false?

On the one hand:
the string can be converted to an array (but not all elements) - so can be successful.
On the other hand:
It could be important that all elements of the string are converted

So the proposal:
When the StringToArrayOfLint returns the number of converted elements, the user can decide by his own how to handle it

• 0 : means not successful
• StringToArrayOfLint() < lengthOf(arr) means: all elements > lengthOf(arr) are valid
• StringToArrayOfLint() > lengthOf(arr) --> can't happen

For some usecases it is necessary to switch from STRING to WSTRING or some other type to WSTRING. This functionality is not provided by the official AX packages. The proposed way to do so is to create a STRING-TO-WSTRING conversion to avoid duplicating code and create general purpose code.

Example '200' will be converted in '2';

Having a code snippet like this:

  VAR 
      str: STRING := '[12, 345, 6789, 56789, 123]';
      arr : ARRAY[0..3] OF LINT;
      succes: BOOL;
  END_VAR
  succes := StringToArrayOfLint(str, arr);

I expect, that the function StringToArrayOfLint returns false, because, the destination array (size) can not store string (5 elements),
