Mmm. Sorry, I didn't think of that. I also noticed I pasted it wrong into
the signature box. This one should be fine (I hope).
Thanks

It's still not right. Anyone know how to fix this?

rgb 9 is also shorter and readable
perhaps your problem with splitted lines depends on default line length in your
Outlook - but it is rather off topic

I don't understand the use of '?' and 'B.y'
Could you maybe explain it to me?

That's OK, I've sorted it out.
Thanks for all your help :)

in your original sig there was assigment
#local B=B-(2*(B-S))*((vlength(B-E)>vlength(S-E)));
expression vlength(B-E)>vlength(S-E) is logical
and can return 1 (true) or 0 (false)
therefore you can change it to:
#if(vlength(B-E)>vlength(S-E))
#local B=B-2*(B-S)*1;
#else
#local B=B-2*(B-S)*0;
#end
and it is eqivalent of:
#if(vlength(B-E)>vlength(S-E))
#local B=B-2*(B-S);
#else
#local B=B;
#end
now, you must know that construction
A?B:C is eqivalent to #if(A) B #else C #end
such equivalent is very popular in programing
(not only POV script language)
(it is described in POV manual under "Float Expressions")
therefore you can write just
#local B=(vlength(B-E)<vlength(S-E)?B:2*S-B);
I have also changed condition for while
from #while(vlength(B-E)>.1) to #while((E-B).x>.1)
Considering that you are going from B to E
you can take length between B and E
but you can also take segment BE
and take one of coordinates

Thanks for fun :)

Those two things aren't entirely equivalent, unless you can guarantee that
E and B have the same y and z coordinates. The substitution might be good
enough for this purpose, but it won't work in general.

I'd like to add a cyan 'N' before the 'X' and keep it at four lines, but I
think that's pushing it a little... ;)

of course, this shortcuts was connected with sense algorithm

perhaps you can achive N with part of X, something like:
/\/ /
/ /\/
