Bash array using system positions limits? [closed]

Here is my array declaration
arraySYSTEM=( "$@" )
It can have up to 10 "system position(?)" members.
I'm using it to build text parameters passed to whiptail function. Then I select the parameter using whiptail checklist (menu). In checklist I can have unlimited number of parameters using $number syntax - such as $16.
How do I modify my arraySYSTEM declaration to have more that 10 members in an array?

If I code this way $10 it fails - highlights the "0" so $10 is OK. Perhaps using wrong syntax WAS my initial error.

You can have any number of entries in an array. For example:
$ set -- a..z
$ echo "$26"
z
(beware $26 is $26 in bash and most other Bourne-like shells)
Ditto for a named array:
$ foo=(a..z)
$ echo "$foo[25]"
z
(The indexing discrepancy is because $0 is special, usually containing the name of the current script.)
