Aha, that would be an issue. Thanks, I'd spent too much time tweaking the
code and looking at the problem to see what's really going on.

I didn't realise I was running over 262 quite so far, I thought I was closer

I don't think I've modified vcs.h, but I'll check that out and fix it before
I repost my progress.
