Re: [Gretl-devel] global series penetrating into functions problem

Dear all, Below is a script illustrating the problem # creates list of all global series function list fun1(void) list retlist = seq(1,$nvars-1) return retlist end function # identity list function function list fun2(list a_list) return a_list end function # checking function function void fu(string name) catch eval @name err = $error if err printf "Variable %s is not defined\n", name endif end function #contaminating function function void spoil(void) list list1 = fun1() list list2 = fun2(list1) end function ###### example nulldata 20 set seed 13 x1 = normal() # before fu("x1") # looking at x1 print x1 # spoiling spoil() # after fu("x1") On the first run fu("x1") does not know global series 'x1' but after running spoil() fu("x1") knows and evaluates x1
