Re^2: Iteration condition...

The trouble with using the flip flop directly is that it's still true when /$Finish/ matches, but the OP wants $State to be false when /$Finish/ matches. To account for this, my solution says ( ( /$Start/ .. /$Finish/ ) && ! /$Finish/ ). The inner parentheses are necessary because && binds tighter than the flip flop. Without them, it means ( /$Start/ .. ( /$Finish/ && ! /$Finish/ ) ), which is true at /$Start/ and then never turns false.

You're quite right. Gotta love boundary conditions ;-) As an alternative to the parentheses, you could replace `&&` with `and`, which has low enough precedence: `/$start/ .. /$finish/ and !/$finish/`.	[reply] [d/l] [select]
