Hello, the title says it all - is there a way to append a list in UR script? Add a new member to it after it has already been created? Or is it at least possible to declare an array with size determined by a variable? I thought i could kinda do it with integer\_to\_binary\_list but it always declares an array of size 32

Hi Peter,

Welcome to the madness. Hopefully we get this feature soon. See below:

The only thing I’m missing is how to initialise an array of unknown size. Like when on any programming language you do something like new\_array[10] Is this at all possible on URScripts?

We have a script we use that allows you to generate scripts of a size with a type already populated.

You can read more [here](https://forum.universal-robots.com/t/how-can-i-create-an-dynamic-array-in-urscript-or-is-it-possible-to-create/8695/4). If you’re interested ping me and I can get you the code.
