getting the number of dimensions in an array on the fly?

[Pete]

No, good sir, I think you got it. Is an array 1-dimensional, 2 or 3? 

I have a case where an array is passed in and it could be any of those.

I guess the simplest way to tell (for now) is the On Error method. 

As you say, we could reserve the first element of the first dimension of all arrays to hold that info, although that would make more work having to modify all routines that return arrays, and also be harder to understand later on for someone else reading the code. 

Thanks for lending your brain to this!

You're welcome. I've loaned my brain out lots of times. How do you think zombie movies originated?
