in reply to Re^3: Combine line segments to form a single line
in thread Combine line segments to form a single line

Thanks choroba, I'm amazed how quickly you worked that. I will try to understand your code to solve my next problem but in the meantime I'll tell you what it is: when there is more than one line the code seems to go into an infinite loop - how to break out of the loop in that situation? (and sorry for being a pest)
my @AoA = ( [11,29, 10,25], [15,35, 11,29], [15,15, 11,21], [10,25, 11,21], [15,35, 21,39], [25,40, 21,39], [21,11, 25,10], [15,15, 21,11], [35,35, 29,39], [29,39, 25,40], [35,15, 29,11], [25,10, 29,11], [40,25, 39,29], [35,35, 39,29], [39,21, 40,25], [35,15, 39,21], [61,29, 60,25], [60,25, 61,21], );

    My version of the code stops with the following error:
    No solution for 39 21 40 25 39 29 35 35 29 39 25 40 21 39 15 35 11 29 +10 25 11 21 15 15 21 11 25 10 29 11 35 15 39 21.
