Saq,
You have thrown the cat amongst my pidgins here. I am keen to see If I can
use this design to generate an end of process. There were features in the
old TWC for each tiddler macro we are yet to recover.
If you make a tested demo example of this code pattern please share.
However I realise my own recent post to Werner allows a test for 1st and
total count (last) to trigger beginning and end processes.
Regards
Tones
