Storing data in Vars of the Geometry App?

[Arno K]

Well, this turned out to work fine, thanks Tim, but for convenience reasons I simply did something like "Instruction(3) in CAS and got the string:
"GD:= element(0,15,3.0); // 00000000) v(1) a(t(2) s(5) p(1) b(0) e(10) S(1)) "
where clearly "GD:=" had to be deleted. I reused this string after the necessary modifications. My question now is: What is the meaning of the additional parameters, clearly the first one is the color, v(1) seems to be visibility and the rest?
Finally I thought Geometry bases on CAS and INPUT does not work there (I haven't tried that till now), here it works fine.
