Yes, so I’d feel a lot more comfortable if I can give a bigger max than 2^32 (which I expect I can, but want to check). I found that in Racket v6.1.1 the max is 2^31 - 1. In v6.1.1.8 all I’ve determined is that the max is somewhere between 2^55 and 2^56, on the machine I have access to at the moment. I’d be perfectly happy to take 2^55 as the constant, IF it will work on all machines; that’d give 1.1 billion years to implement an improvement. With a coffee break, even. Best, jmj ____________________ Racket Users list: http://lists.racket-lang.org/users
