Please include the autosimplify(#) xcas command to set or not the simplification

In the following code the line,

autosimplify(2); // nop=none, 1=regroup, 2=simplify

is not yet interpreted on hp-prime

When changing the flag autosimplify(#), change the output please check the following code in xcas, varying the autosimplify(#) argument

PHP Code:

#cas
        test_simplify_flag():=
    BEGIN
        
        local  list0,expr0;
        local x, y;
        assume( x, symbol ); // purge(x);
        assume( y, symbol ); // purge(y);
        
        autosimplify(2); // nop=none, 1=regroup, 2=simplify

        print;
        print("Solving a system of two equations.  
Solve the  following system  [ y=x², y=2x+3 ]");

        list0 := [ y = x^2, y = 2*x + 3 ]; print(list0);

        print(""); print("> substitute y = x² in y = 2·x + 3");
        expr0 := subst(list0(2),list0(1)); print(expr0);

        print(""); print("> substract 2·x + 3");
        expr0 := expr0-(2*x + 3); print(expr0);
        Return expr0;
    END;
