Hp-50 remembers all previous graphed functions

[Jan5]

Hi,

When I do graphing by pressing Y= and entering an equation, the equations seems to be stored because the counter keeps increasing (i.e. it started with Y(1) = whatever you want to graph, and now it's Y(130) = whatever you want to graph).

If I press "Choose" from the Y= page it will list all the previous graphs I have entered and let me choose a previous one.

Is there a way to not have this functionality? The calculator seems to have to be busy for a while before graphing a new equations so it takes longer - and I don't usually need previous graphs.

I have looked through the FLAGS and CAS and DISP settings but couldn't find anything.

Any help would be appreciated. Thanks.
