Exactly what I was looking for. Bookmarked.
Thankyou Hans and everyone for your suggestions.
To put it in context... I was attempting to solve/answer
an occasionally recurring problem for someone.. "My Pd
file is corrupt and all the objects have vanished"
I solved this before by trial and error, matching up
canvas statements with restore statements (It does indeed
work as I thought, pretty much).
