bool = CValueSet:SetType( strNewType )

    Sets the type of values in the set, where strNewType is "number", "integer", "string", or "boolean".

    On failure, returns boolean false.

-- 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("Count= %d", S:Count())

-- result: Count = 3

S:SetType("string")

-- changes the CValueSet object to "string"

Printf("Count= %d", S:Count())

-- result: Count = 0 (the CValueSet was emptied)
