Thanks for that, so far, and for clarifying that #5420 is not absolute. This is 
a big step forward.
Now you have me intrigued...
so how do I get absolute?
I had imagined everything would be absolute internally, then offsets would be 
added to get current workspace co-ordinates, but if G28 and G30 work in 
absolute, where do they pick up those values from? So that led me to think 
there was a set of parameters which always held current absolute, with no 
account being taken of offsets (so that absolute always means absolute).

Regards,

Marcus

(debug, X = #5420)

both #5420 and #<_X> seem to show current workspace position, not absolute.
Do you want absolute? There are ways.
