find and index functional cmd

[compsystems]

Hello BP, the find and index functional commands are not working

D_ := set[ "H", "E", "L", "L", "O"];
find("L",D); find("O",D_);
E_ := [ "H", "E", "L", "L", "O" ];
find("L",E_); find("O",D_);
index("L",E_);

What do you think is wrong?

a list of numbers or symbols, FIND CMD if it returns a list of the positions of an object to be searched, but a list of strings, FIND CMD returns an error


G_ := [ H,E,L,L,O]
find( L, G_ ) [↵] [2,3]

E_ := [ "H", "E", "L", "L", "O" ]
find( "L", E_ ) [↵] " Error: Bad Argument Value" => [2,3]

But that's what I get: [2,3]

in the PC version did not work, reset cache works in the online version,
but the result of the third instruction is not displayed, that is, the output of index(E_,"L"); is not shown , Is this a bug?

test
E_ := [ "H", "E", "L", "L", "O" ]:;find( "L", E_ );index(E_,"L");
