For loop with shift registers and an empty array as indexer

[DavidBoyd]

OK, there is no other place than right here that I can ask this obscure a question:

When mentally evaluating code with a an autoindexing for loop that also carries shift registers, and contemplating the dataflow if an empty array should happen along at runtime...

Does anyone else in the LabVIEW universe (besides me) have a flashback to those old MAD magazine inside back covers?

Thanks, it's been a long day,

Dave

....must enable constant folding for this to make sense.

No,  the shift register is one location in memory.  once you write to it it has a value.  tunnels each get their own buffer so outputs are only written when the loop actually iterates or else they have the default value for the datatype.  crystal clear.

Ummm, Jeff, it's BreakPoint. It was my attempt at über-geeky humor.

Not to belabor the point, but I've been on the LabVIEW bus since version 4, ca. 1997. So I think I know about SRs vs. tunnels.

Yes, whenever i try to understand recursive functions ...

OK .  thinking that way.  And trying to be funny.  How small is that bus?

32 seats.
Thy are working on making it 64 seats, you only can't exit it at every stop from the new seats.

My bus has 64 seats, all occupied by either tall thin people who stand straight up and seem very active, or short round glum looking people. And every time the built in clock ticks a second they all rapidly change seats. Sometimes I think I see patterns to the chosen seat positions, but it mostly looks random...

There are no bozos on that bus (an homage to "Firesign Theatre" for those old enough to remember, who, if they listened to FST are able to remember.
