Command needed for striping brackets

#cas
GET(r,u):=
BEGIN
RETURN r(u);
END;
#end

For example:
GET({8},1) gives 8
GET([8],1) gives 8
GET({8,2,6,4,7},3) gives 6

----------------------------------

This doesn't work on my Prime. No matter how using Get/or get in Home or Cas,
this command is inactive. My software has just been upgrade to 2.1.14425 (2020 01 16). Likewise this command was also inactive on the calculators former software.
I invite others to confirm here what their Prime does and don't in regard to striping parenthesis from numerical. The newest "Prime G" could be corrected.
I think it unwise trying install Prime G software on my older not a "G model hardware".
