Re: array(0, {800,600}) is easier.

Lucius,

I wouldn't be surprised if I am woefully misunderstanding something really
basic, but it seems to me that neither your "repeat" example nor your array
function yield the 8x10 array you want.  Doesn't  "repeat(repeat(0,10), 8)"
give  a sequence of TEN zeroes, repeated 8 times, instead of the 8 zeroes
repeated 10 times you show in your example?

Ditto for your array function when I run it & display it with smart_print.
Looks to me like "for A = length(dimensions) to 1 by -1 do" should be "for A
= 1 to length(dimensions) do" ?
