Example

The following example creates a CValueSet S, adds members to it, then removes the member at index 2:

S = new_valueset()

-- constructor, default to values of type "number"

S:Add( "key 1", 15.5 )

-- add a key and value

S:Add( "key 2", -7125.23 )

-- add a key and value

S:Add( "key 3", 0.923 )

-- add a key and value

Printf("Member= %s, %lg", S:GetAt(2))

-- result: Member= key 2, -7125.23

S:SetAt(2, 15.6)

-- set the value at index 2

Printf("Member= %s, %lg", S:GetAt(2))

-- result: Member= key 2, 15.6
