Hello all. I’m am trying to change data in a recursive way so that I can update a list in multiple operations. For instance: having a list form 1,2,3,4,5,6 Changing the 2 to 6… AND THEN changing the 9 to 50 and so forth , remembering the prior changes each time. Obviously, this means that the ou…

Well … This has 2 options: the fire and forget (i.e. auto, piece of cake > see attached). the interactive (requires advanced to expert level in order to cut the mustard properly). Briefly: for each execution store volatile data as persistent (in a suitable parameter) and read them (by accessing t…

Please have a look at he newly inserted image. The idea is to trigger the operations manually each time with a button. Not a loop with auto iterations.

Thank you, Peter. Unfortunately, my coding knowledge is not great:) I tried operating your def bit didn;t really understand it. Please have a look at the new image I posted for the explainer. Your help would be greatly appreciated.

[image] Gong_Barny: really understand Well … it’s simple: working solely in a demo mode (i.e. not accepting any user input) it makes integers 0 - testN and stores them in a history tree at branch 0 (called Loop). Then sets Loop 1. Then for each next Loop (<Loops) reads the history at branch L…

Thanks Peter, the idea is really simple here, probably simpler than what you wrote. I want to replace a value by on demand and have that value changed so I can make the next change. Let’s give an example: You have a list of phone numbers and John just notified you he changed his number. So you …

Well … that does that stupid C# (playing randomly with these #%#^% integers). The diff is that John is John (i.e. not a Random thing) meaning that he has an index assosiated with him (in the phone List … or wait: in fact in a Class that tells you the customer ID, the Name, the Number, the Address, …

if you want to manually confirm each iteration by (for instance) clicking a button, then you can use something like this, and click the play button on the Trigger component (right click on the Trigger and set to Manual) : [image] the Counter component comes from Kangaroo 1 but the main question …
