The function adds new value to a string array but only if that value doesn't exist in it yet. So, if the whole array is populated using this function only, then, finally, all its elements will be unique. You need to have the function uf_value_exists_in_array() prior to adding uf_add_unique_element_to_array(). It has 2 overloads - for string and long data types:

String:

Code: Select all
/**********************************************************************************************************************
Dscr:         Adds new value to a STRING array but only if that value doesn't exist in it yet. So, if the array
            is populated using this function only, then, finally, all its elements will be unique.
            Another overload does the same for LONG array.
***********************************************************************************************************************
Arg:         as_val - added value
            rs_arr[] (ref) - array to add value to

**********************************************************************************************************************/
long         ll_new_upper_bound
DataStore   lds_temp

if this.uf_value_exists_in_array(as_val, rs_arr[]) then // uf_value_exists_in_array(): http://code.intfast.ca/viewtopic.php?f=4&t=93
   return
end if

ll_new_upper_bound = UpperBound(rs_arr[]) + 1
rs_arr[ll_new_upper_bound] = as_val

return

Long:

Code: Select all
/**********************************************************************************************************************

            is populated using this function only, then, finally, all its elements will be unique.

ll_new_upper_bound = UpperBound(rs_arr[]) + 1
rl_arr[ll_new_upper_bound] = al_val
