Yeah, I found that out the hard way. I saw “callcode” and that it wasn’t used and thought “is this some weird reserved B09 thing?”

But is it doable in BASIC09? Two workarounds on how to deal with INTEGERs like this, but I suppose IF one needed that, they wouldn’t use INTEGERs — a type that only represents the -32K to +32K.
