maximum no. of sequences in a sequence structure

[johnsold]

The maximum number I use in my code is 1.  The usual number is 0.  It is used to force data dependency.

The one exception is when I running a timing test on pieces of code to see which is faster.  Those programs use flat sequences with n+2 frames where n is the number of  pieces of test code.

tst,

Please tell me you made this VI using scripting, and not by manually adding 10000 cases!

If you did the former, did you try and see how many you could add before LV gave up completely?

As a glutton for punishment I tried clicking on the case structure, it listed all the cases nearly instantaneously on my PC, so then I decided to convert it to a flat sequence and that did the trick: LabVIEW thought for a while then just terminated

What's "scripting"?

Adding it is simple - you just add a few cases every hour during breaks and in a few months you have your structure. 😄

I initially let it run to ~20,000 but then tried to look at it and crashed LV (hence the warning). The property itself is an I32, so it should be able to get to ~2 billion frames, but there are probably other limitations which will prevent you from getting that high.

I tried to get that many cases with LV 7.1.

Having accomplished to create a enum with 10000 enties (named from 0 to 9999 so I'm sure I don't miss one). I wired the enum to a case structure and tried 'add case for every value'.

All I got was one new case with the name "".

Are state machines limited to <10000 states in LV 7.1.?

10000 stars for making 10000 sequences, tst!

BTW, how did you make it, scripting... ?!

I think I read that the LV block diagram is limited to about 65,000 pixels wide. If the stacked seq was wider than 65 pixels (about two sub-VIs in width) then the conversion would have run into the diagram size limit.

Scripting is where you train a monkey to use a mouse and repeatedly do right click-->add case after

These modern monkeys are really smart, after only a few bananas they get the idea and can produce some LabVIEW. Trouble is when senior management gets wind of these code writing monkeys they try and steal them away from me to produce test applications!

Hey,

@Ben: I think the limit of the block diagram width is 65.498 pixels. However if you test it with a flat sequence it becomes invisible over a width of 32600 pixels (LV8.2.1)

I still haven't heard from the poster why they want to know this in the first place.
