Many thanks Paolo, I'll certainly check out the RMF bits and revisit ANTMON.
With XRC in mind, could anyone point me to a description of the LONGBUSY (I've only been around XRC for 10 weeks). I did look at the ANTMON figures for the related secondary volume and saw very low consistency delays and no appearances in top 25 volume list. LONGBUSY looked to be 0 (but as I don't understand LONGBUSY - I may have misread that as well).
