List of message without duplicates

It is not clear what names you are referring to, but a [zl thin] object outputs whatever list it receives and removes duplicate entries, so it might help in your eventual solution.

Thx TYLER the object works only as it eliminates the previous list. I need you to receive messages with texts and to accumulate them in the list when they are new texts. if you enter a repeated one ignores it

Use the "names" ????? (that are symbols right ?) as addresses in coll.

[zl thin] is a key, but you have to store growing list. Then you can display it in any way.

thanks to all!!!!!! Is Possible this in a dict.view object!!!!

yep, even easier:
