I've been experimenting with stacked subframe machines that are only 2 pixels long, but consist of 4 pixels in total.  Thanks to the subframe order, an upward-pointing subframe ARAY (or UPSFA) and rightward-pointing subframe ARAY (or RPSFA) are easier than a leftward-pointing subframe ARAY (or LPSFA) or a downward-pointing subframe ARAY (or DPSFA).  I've successfuly made a LPSFA that obeys the subframe order, but every DPSFA prototype I come up with fails to do so because the ARAY has to have a larger y coord than the copied solid SPRK in order to point down.  Is it possible to circumvent this and; if so, how?  Here's the save:

P.S. I think I've gotten left and right mixed up; is left and right in tpt defined as your left and right, or your computer's left and right (you and your computer always face opposite directions).

It worked, thank you for your help.
