The longer a line the more difficult it is to move the focus to the beginning of the next line when reading.
Hmm, then I must be doing something wrong, I do not fully fill program lines... ;-) Or my comments are too short. I do not think, this is an issue, to catch the next line, if the program text is well structured... Nevertheless, I do understand this is a force to make the text structured...
Therefore wide news papers use columns. Also consider source code printed on paper.
I do not remember when I did that. But if anybody does then it is a reason.
Or is the reason much deeper? Or, is the bound set to 78 characters just because it is as good number as any other?
Unlimited length (as for plain text) would be an option if automatic wrapping wouldn't destroy the layout.
Yes, yes... Anyway, I don't like 1024 characters one-liners anyway. ;-) :-) DuĊĦan
