There is not variable registry. But you can use a Map. There are tons of examples on the forum.

thx for reply. And for the hint. I have a rule running, but it’s about 350 lines of code. So now I try to find another solution. But my knowledge about scripting and programming are very small. Even if I try to structure my rules, at the very end it’s mostly “spaghetti-code” :smirk:. What I’m look…

thx. I already tested with Map (and HashMap) and Arraylist, like below. And as you said there are tons of examples. import org.eclipse.smarthome.model.script.ScriptServiceUtil import java.util.Map var Map<String, String> mDay = newHashMap var logCount = 8 var Number logYes = 1 // it's no boolean -…

[image] fibu-freak: Maps seemed to be very slow (or need a lot of resources) o I suspect you had something else going wrong because Maps are nearly the fastest type of dates structure for reason access there is in all of computer science. Where you trying to lead it up with primitives? Are yo…

Sorry Rich. My fault. My first intention was not right. Maybe there was a knot in my “spaghetti-code” or/ and in my brain :thinking: :crazy_face:. But after you have pushed me (one more time) into the right direction, I first read (as you said) in the DP an then began thinking about recreation of t…

Not really but I think you are looking for Design Pattern: How to Structure a Rule. If I understated what you are asking, the answer is yes.
