Stream Class

Here's an example:

Class User.NewClass1 Extends %Persistent
{

Property streams As list Of %Stream.GlobalCharacter;

ClassMethod Test()
{
    do ..%KillExtent()
    
    set obj = ..%New()
    set stream1 = ##class(%Stream.GlobalCharacter).%New()
    do stream1.WriteLine("Hi")
    set stream2 = ##class(%Stream.GlobalCharacter).%New()
    do stream2.WriteLine(123)
    
    do obj.streams.Insert(stream1)
    do obj.streams.Insert(stream2)
    write $System.Status.GetErrorText(obj.%Save())
    
    kill
    
    set obj = ..%OpenId(1)
    for i=1:1:obj.streams.Count() {
        write "Stream #", i, ": ", obj.streams.GetAt(i).Read($$$MaxCacheInt)
    }
}
}
