So if '<' works then that's better in this context. (In a different context, or in the same one there definitely was a problem with using '<', but I can't remember the details, it's too long ago we discussed about this; maybe it even was a problem only with some binutils versions. So I'd suggest using the more obvious way until problems reoccur, and then document why exactly using relational ops was a problem ;-) ) Ciao, Michael.
