How to shift content in Array of String (LAD)

cobra_control Posts: 6 Rating: (0)	Hi! I have an S7-1200 PLC and I have a little data handling problem. There is an array which contains 30 Strings. I need to shift the content (right or left I think it's not that important now) in the way that the last String should be deleted so I can insert another String to the first place. And so on and so on.... Is there an easy way to do it ? Thank you for the help !
