Right Click Case Statement suggests replacing with a Stacked Sequence !!!!

[Ray.R]

I must admit that I don't usually right click a Case Structure often with the intention of changing it to something else.

A recent post made me look at the Case Structure to suggest how to change it into a "Disable DIagram Structure", so I figured maybe right-clicking it would offer that choice. ...

To my horror, the only replace choice is the most horrible of all structures!~!~!~!  the Stacked Sequence!~!  😠

Maybe I should suggest to change that in the product suggestion thread. 

Did other notice that before?  Yikes!  😮

I agree there is little logical resemblance between a case structure and a stacked sequence, so I don't quite see the usefulness of this option. I think it is very old, though, so it might have been retained for legacy reasons. Of course there is also the reverse, converting a stacked sequence to a case structure. I've never tried it but I wonder how it would handle sequence locals. 😉

I rather would prefer to be able to convert between case structures and event structures, something we cannot do. 😉

I can see a use case, if you have a for-loop with the iteration index linked to the case selector. Such a structure can easily be replaced by a stacked case structure.

Just because it's a bad programming technique it shouldn't be made impossible.

Really???

A case structure has typically multiple code alternatives wired to the same output tunnels. This is logically incompatible with any kind of sequence and you'll get a lot of broken wires (I just tried it myself). So "easy" is probably not the right word. 😄

I agree with Altenbach which is why I was so surprised.

Even if a For Loop was used to index a Case Structure, any of the exit tunnels would have a value for each of the Cases.  So how does the Stacked Structure stacj up to that?  😉  <pun intended>

Let's assume for a minute the the magic of Labview does convert the Case Structure somehow correctly.  Personally, I try to educate others to stay away from those darn structures...  But it's offered as a selection when right clicking a Case Structure..  So who are they going to believe?  A Stacked Sequence of 3 or 4 frames (max) might be okay if coded properly.  But that is not what I constantly see.  I keep seeing nested S-S 3 to 4 layers deep with as many as 100 frames!!
