[Jgeneral] Tacit formulation

[Dr. Heinz Schild]

I want to read a list with coordinates (x, y) of unknown length from the 
clipboard into an iPad and transform it into a table with 2 columns.  The 
following line works:
((<.-:# Zi),2)$ Zi=. 0". jfromcb ''
But is  there a better way using only a tacit formulation? 
Heinz
