As I said in my reply to swampyankee below, I knew what the node was about when I read the title. So, there's a little empirical evidence to counter your opinion that the title doesn't (didn't) say clearly what the node is about.

This kind of "empirical evidence" is 100% meaningless. The node could be titled "Weird Problem", and *somebody* would step forward to say he understood what it was about, from the title. ("I mean, just last week I had this thing happen to me, and I thought, Wow, what a weird problem!")

Objectively, the title "program line" is ambiguous in the extreme. Sure, *somebody* might immediately understand it, either by being on the same perversely obscure wavelength as the poster, or by pure chance, but that does not make the title clear or good.

the fact that you think it is a poor node title doesn't automatically indicate an absolute quality about the title

He didn't reach the conclusion that the title is "unarguably horrible" by subjectively thinking to himself, "Hmmm... what images does this title bring to me, personally, in a free association framework?" Your suggestion that anyone who claims a title is unclear is obviously making this claim based solely on some touchy-feely subjective personal experience is either deliberately obtuse or just plain poorly thought through; in either case, from a linguistics standpoint, it's plain wrong. Objectively speaking, the phrase "program line" has a large number of possible meanings in the context of SOPW, and for every person who reads it and immediately gets the right idea, somebody else will read it and immediately get the wrong idea. No amount of irrelevant "I think, you think, works for me, works for you" subjectivist drivel will change that.
