max/min of more than two values

[SteveVijayan]

In my model, I have equations where I use min and max with more than two values. For example, max(A,B.C). I am getting an error. It looks like vensim can find min or max of only two values. Is that correct?

And if so, how to find min/max of more than two values?

Thanks,
Steve

What version are you on? Recent 10.x can handle variable arguments.

You can always write MIN(a,MIN(b,c)).

Thanks Tom.

I have an older version - 7.3.5.

Are you referring to vmin/vmax in version 10.x?

Thanks,

No, VMIN/VMAX are for working with subscripted/arrayed variabled.

In the latest version of Vensim, you can use
some value = max (a,b,c,d)
Prior to this, you would need to use
some value = max (a,max(b,max(c,d)))

Thanks Tom.
I have not extended maintenance for a few years.
If I extend maintenance, will I be able to get the latest version?

Yes. But you can just nest the min/max calls as well if you need to. Vensim now has a completely different interface to the one you are used to.

Thanks Tom.
If I download the new version, I will still be able to use my files/models created using my current (old) version - correct?

Yes, of course.

Thanks for patiently answering my questions.

v10 is a pretty big upgrade from 7. There will be some interface changes that take getting used to, but it's worth it.
