Existing equations in 35s programs?

[Orome]

The manual for the 35s says that equations can be used in programs, but (unless I've missed it) only shows how to enter new equations as part of a program. I don't see how to use an existing (already defined) equation in a program.

Is there a way to use an existing equation as part of a program?

Good question.

I haven't used a 35s much but not having a lbl to be addressed I don't see how one could call a stored eqn like one could do for a subroutine (that would have a lbl that could be addressed with the desired eqn).

Unfortunately not.
Is it required to select one equation from a list? There was (many years before) few idea/programs how to make a "menu" on HP32SII, it can be same on 35s.
Also you can try to make it with (i) and (j), I am ready to brainstorming about it.

Why not put the equation in a subroutine and call that?

That kind of defeats the purpose of avoiding having to include it in a program in order to use it.

The question is whether an existing equation that hasn't been included in a program can be used in a program.

My bad. I was thinking the object was to be able to call a subroutine to solve an equation. It wouldn't be in the current program and would be available to all programs. Oh well.

I think what the manual was trying to state is that you could insert and use an equation in a program, not use an existing equation from the equation list. AFAIK you cannot use an existing equation from the equation list in a program.
