Thanks for answering!
While I think it's kind of silly that QB64/PE doesn't provide some way to track & test whether a variable is currently associated with a valid image, it's not THAT big a deal, and I'll just keep in mind to make sure to keep track of that. QB64 compiles to C, so I'm not that surprised we have to do some of that manually, the trade-off being that because our programs compile to C, they can be FAST!
Thanks again guys
