From Clomosy Docs

Array means many variables of the same data type. Array variables are like a list with a sequence number. Items belonging to this list are also accessed by their sequence number. Another structure that enables the use of Array on Clomosy is the TclArray structure. There are different definitions according to the data type. These;

Feature Use of Definition
TclArrayInteger arrayInteger : TclArrayInteger; Array definition indexed by integers.
TclArrayString arrayString  : TclArrayString; Array definition indexed by string.
TclArrayDouble arrayDouble : TclArrayDouble; Array definition indexed by double.
TclArrayBoolean arrayBoolean : TclArrayBoolean; Array definition indexed by boolean.
TclArraySingle arraySingle : TclArraySingle; Array definition indexed by single.
TclArrayWord arrayWord : TclArrayWord; Array definition indexed by words.
TClArrayExtended arrayExtended : TClArrayExtended; Array definition indexed by extanded.
Create array1 = TClArrayInteger.Create; An object is created in the form.
Count array1.Count; The size of the array is taken.
Add array1.Add(50); The value 50 is added to the array.
GetItem array1 (50 , 100, 70, 12, 3) array1.GetItem(1) Used to access the items of the array. This will return the requested item one by one, no matter how many items are in the array. I want to get the data in the 2nd element of the sample array.
SetItem array1.SetItem(1,25) //array1:TclArrayInteger Value assignment is performed to the array element in the array used. The first parameter represents the index number, the second parameter represents the value assigned to the selected index number.
RemoveAll array1.RemoveAll; It is used to delete the entire directory.
RemoveAt array1.RemoveAt(5); "RemoveAt" is used if you want to delete data in an index of the array. The return value of this operation is returned as boolean. The return value is "True" if data deletion has been performed. If this index does not exist in the array and cannot be deleted, it returns "False".
Destroy array1.Destroy; It is used to delete an object from memory and free the memory.

Example

var
  array1 : TClArrayInteger;
  i : Integer;

{
  array1 = TClArrayInteger.Create;
  array1.Add(20); 
  array1.Add(30);
  array1.Add(17);
  array1.Add(23);
  
  for (i = 0 to array1.Count-1)
  {
    ShowMessage('Value: '+IntToStr(array1.GetItem(i)));
  }
}
