use of multiple identical objects in spin2

when I have 4 of these X Band devices hooked up, and code it this way, does it use 4x the memory? Do I have to make a clever multipin X Band Object to make better use of memory?

    Pretty sure uses 1X the memory, unless you have a VAR section.
    Each would get its own copy of things in VAR sections...

    At least, that's the way remember it...

    Not hard to test. See how much the compiled file size increases when adding first object compared to adding more copies.

    Code and DAT sections are shared between instances. The VAR section of the object is duplicated to be unique for each instance.

    Quick test with my version of the x-band object.

    #    Code  Delta    Vars  Delta

    oh, right... thanks all. I should pay more attention to the "Object Info" viewer.
