Sorry, I didn't realise. Obviously they're easy for me. Could we possibly improve them somehow, since I find it difficult to think things through without some sort of diagram? For example, would it help if the actual BOLs and the xdisp BOLs were written on separate lines? Something like this: nlines = 3 Act: WS L1 C C2 C3 8. --------------------------^----------------------\n-------it,T------- Xdi: B A A2 C C2 C3 , where ^ is the starting point, T is the target BOL and "it" is where Fvertical_motion moves `it' to?
