Storing data in Vars of the Geometry App?

[cyrille de brébisson]

Hello,

What most people do not realize is that GA, GB... contain the RESULT of the evaluation of the various lines of instructions present in the geometry symbolic view.
so, doing GA:=point(1,1) means that GA contains the calculated value of point(1,1), not 'point(1,1)'... a little bit like if F1(X) was containing a function NOT dependent on (X).

This is why the Instructions function is there, to allow you to modify the instruction list.

to get back to your question, when accessing Instruction in a textual fashion, the syntax is from memory:

Name:=function // c(color) v(0/1) p(0-7) f(0/1) t(0/1) l(0/1) t(f(font) d(dpi) x() y()) a(t(0-3) s(0-15) p(0-15) b(real), e(real), S(real))
where v is for visible
p is plot type (used for points)
f is filled
t is traced
l is legend visible
t is for text positioning with font, dpi, x and y positions provided
a is for animations with type (none, once, loop, back and forth), s for speed, p for pause, b/e/S for begin, end and Step
