Hi Tom,
in all likelihood the cause of your confusion is the use of an unofficial and clearly outdated website with questionable content.
In your contributions you mentioned the site http://www.hp-prime.de. That site was never an official site from HP. Looking at the so called "impressum", that site is provided from MORAVIA EDUCATION, Olomoucká 1213/83, 627 00 BRNO (CZ).
The content of the page has probably not been updated for a long time, for example the linked programs refer to versions from 2018. It is therefore not very useful to use the content of the page as learning material.
This is my personal opinion.

Thank You, I didn't know that.
N.B.(Note Briefly) the Where works on the regular page of HP Prime just not in Functions.
You probably already know that.
Thank again.
