Lego NXT Bricx Arrays

[pevecg]

Hello,
I am trying to create a snake game using Arrays, but I have come to an problem since I cant find an function(or knowledge) how to completely remove index from an array or how to create an workaround. The index that I would have to remove would always be 0. Thank you for all the tips

Problem may be in firmware. If it's standart, you can't use two dimentions arrays.
