Hi John,
Thanks for that shaking :-)
You are right my problem is elsewhere in the program. I just assumed this was
the problem because
of everything I was reading about floating point problems. I think I have
learnt a lesson here.
I'll read the gdb manual to figure out how to step over and not step into.
killfile me it's for my own good.
cheers
