Deleting an array shuffles the array numbers

Hi!
I want to use arrays in some CFs as follows:
let ( [
$i = $i + 1 ;
$array = if ( $i = 1 ;
$array = BE_ArraySetFromValueList ( "1¶2¶3¶4" ) ;
$array ) ;
...some calculations using BE_ArrayGetValue ( $array ; $i )... ] ;
if ( $i + 1 > BE_ArrayGetSize ( $array ) :
let ( [ result = whatIwant ; $calculatedResults = "" ; Be_ArrayDelete ( $array ) ] ; result ) ;
doItagain )
)

Checking if there are still values in $array: there are.
As far as I understand it, $array is a number that's assigned by BE_ArraySetFromValueList.
What is wrong with my thinking?
TIA

The following code should delete both arrays, when one is left active:

Let ( $arr1 = BE_ArraySetFromValueList ( list ( "abc1" ; "Lis01" ) ) ; $arr1 ) & ¶ &
Let ( $arr2 = BE_ArraySetFromValueList ( list ( "abc2" ; "Lis01" ) ) ; $arr2 ) & ¶ &
BE_ArrayGetValue ( $arr1 ; 1 ) & ¶ &
BE_ArrayGetValue ( $arr2 ; 1 ) & ¶ &
BE_ArrayGetSize ( $arr1 ) & ¶ &
BE_ArrayGetSize ( $arr2 ) & ¶ &
BE_ArrayDelete ( $arr1 ) & BE_GetLastError & ¶ &
BE_ArrayDelete ( $arr2 ) & BE_GetLastError & ¶ &
BE_ArrayGetValue ( $arr1 ; 1 ) & ¶ &
BE_ArrayGetValue ( $arr2 ; 1 )

output is:

18
19
abc1
abc2
2
2
0
0
abc2

---

The "abc2" value is coming from $arr1 which it should not have as it was deleted.
