testing for array existence

BlitzPlus Forums/BlitzPlus Beginners Area/testing for array existence

Hi probably a dumb question but I just started using the product a couple weeks ago. and I was playing around with a breakout type game. Anyway I created my bricks as an array and I was wondering if there is a quick way to test if there are any bricks left.
something if bricks.items = o then
;level complete
else
updatearrayofbricks()
endif
