Is Geometry.Instruction(n) buggy?

[Angus]

hello everyone

I kept playing with Instruction() and noticed that adding a String to the command table is not possible. Giving an error when Geometry app is active.

with Geometry App active
Geometry.Instruction(1):="x" ---> "Error:Invalid Input"

with other app active, say Function
Geometry.Instruction(1):="x" ---> table(1 = "x"), but when going to Geometry/Symb there is no entry visible.


If n==0 Instruction(0) should append a String to the list.
Now Geometry.Instruction(0):="x^2" ---> table(1 = "x", 0="x^2"), still nothing visible and also "Error:Invalid input"...



Is there a chance I did not understand Geometry.Instruction(n):=STRING correctly or do we have to consider that one buggy?
