Yes, well, that's what you get when you try to translate code written for a language that supports arbitrary bb graphs to a language that does *not* support arbitrary bb graphs... I remember that way

Thank you -- works fine under Linux. I'd like to add this to the next Coco release. But it'll break on Mac OS X in 64 bit mode, since the assembler syntax is different. I hope this works (but I can't

You should look at the Lua/Tk binding for ideas.. The method above is much simpler than what you have to do if you want to walk the table entirely from C-code. I have some loops in my software which

Okay, I thought that it had said "the set of all positive integer keys" there. In that case, drop the floor() check. I'm minimizing the risk of overflow. As I commented, my current scheme requires a
