Help with Arrays??

Wow. The following meaningless script fails, (though it doesn't  
produce an error) ie. the result is simply 12 in the message box, the  
keys of the array are not sent to the message box...

on mouseUp
   showArray 12,makeArray(12)
end mouseUp

on showArray 12,tArray
   put x & cr & the keys of tArray
end showArray

function makeArray x
   repeat with n = 1 to x
     put 0 into tArray[n]
   end repeat
   return tArray
end makeArray


while

on mouseUp
   put makeArray(12) into tArray
   showArray 12,tArray
end mouseUp

works just fine...

Maybe this is a bug. Anyone else come across this?
