Hello, I have a problem about subscript variables. First Question : If I use a variable named Subscript[x,1] , (typed in with Ctrl _) I can affect a value to this variable, get value of expressions involving this variable, clear this variable with . but not with Clear[] ! This variable is not given when I ask Names["x*"] and I cannot get information on it with ?. Second Question : If I use such a variable in order to define a function with f1[x_]=x^2+1 I cannot clear the variable with f1=. (of course, just above f1 means Subscript[f,1]) Thanks a lot for any help J.Michel CORNIL
