reserved variables
Hi, when trying to store a invalid object on the reserved variables, it should show an error message, plus there should also be a menu to be able to copy and paste the reserved variables
fsolve( θ=10*sin(θ), θ, [5,7.5], bisection_solver) => [7.06817433238,7.06817440689] bisection_solver:="hello"; // do not allow approx_mode:=1; approx_mode:="hello"; // do not allow complex_variables:=0; complex_mode:=0; other variables that are not documented or do not appear in the hpprime catalog. Please hpteam to include them in future updates list of internal variables: approx_mode, complex_variables, complex_mode, all_trig_solutions, angle_radian, with_sqrt, increasing_power, bisection_solver, newtonj_solver, etc.

RE: reserved variables
If such a list were made, it would be very helpful to also distinguish between the ones which can only be used in CAS mode, as well as the builtin named constants (e.g. title which always seems to be equal to 15).

RE: reserved variables
example of use of the flags (internal variables), to show in the history different results or forms, for this reason it is important to include (next firmware) these internal variables that in some cases act as commands
xcas PHP Code: with_sqrt(0):; factor((5*s^2+32*s+45)/(s^3+6*s^2+9*s))
