substring substr get part of a string
-
This is probably obvious to everyone but me but I cant find any hit on google to explain how to get a part of a string into a new variable.
As a reference to what I want to do: in most languages its is called something like substr( stringname, startposition, number of chars )

I was looking for this for 2 hours and after posting I found a solution by chance after 5 min.
I will leave this with my solution if someone have the same problem later.
this page show how it is done in python:

now I started trying to find any function in UIflow that could replicate this and..."bytearray in list xxx get sub-list from # to #" actually writes this code!
