Turf symbol question

[takeout]

Sometimes the ‘T’ will have a circle around it and sometimes a box. Is there any reason for this? Why the two different symbols?

Thanks.

inner = box
main = circle

Could be part of a logic test.

box::inner
circle:: ?

[takeout]

inner = box
main = circle
Thanks again. I had it backwards. You can tell it’s been a l-o-n-g time since I’ve bet a turf race. :D
