Scene file req. Info.

[Perry]

When you view the .SCN file you usually see something like this in the Quadrant block.

QUADRANT 0 0 1 1 islet3s
QUADRANT 1 0 1 1 islet4s
QUADRANT 2 0 1 1 islet3s
QUADRANT 3 0 1 1 islet4s

But recently I ran across a .SCN file with the variation similar to.

QUADRANT 0 0 1 4 islet3s
QUADRANT 1 0 1 5 islet4s
QUADRANT 2 0 1 1 islet3s
QUADRANT 3 0 1 1 islet4s

I don't know why this variation, because I don't understand what the 1 4 & 1 5 last number variations do.
Furthmore my utility FMSXYZ fails to render it properly, though it will pull it up and doesn't crash.
I would like to include the possibility of utilizing these numbers in the utility and will do so if someone will help me understand it.
Could anyone point me in the right direction, or if you know would you educate me?

Thank you;

Perry
