strKey, Value = CValueSet:GetAt( nIndex )

    Where nIndex is an integer in the CValueSet, ranging from 1 to CValueSet:Count. If the index is invalid, nil, nil is returned.

    The strKey is the string key at the specified set index.

    The Value is the set value at the specified index as a number, integer, string, or boolean.

    On failure, nil, nil is returned. Note that this method returns 2 results.

S = new_valueset("integer")

-- constructor for a set of type "integer"

S:Add( "key 1", 15 )

-- add a key and value

S:Add( "key 2", -7125 )

-- add a key and value

S:Add( "key 3", 9 )

-- add a key and value

Printf("Result= %s,%d", S:GetKeyAt(2), S:GetAt(2))

-- result: Result= key_2, -7125
