I'm going to agree with ysth's comment: the node title "program line" was terrible; indeed I feel it fit into sauoq's category of "downright, unarguably terrible", as it was both too generic and to non-descriptive. The title "program line" did not, even vaguely, describe the question.
Firstly, that was itub's comment. Secondly, and more importantly, your opinion about the title is only that... an opinion. Maybe it is inexplicable, but I knew exactly what the question was about when I read the title. I suspect I wasn't the only one. So, it may have been a poor title for you but that doesn't translate to some absolute notion of a poor title.
Retitling should be used only for those cases where there really is no difference of opinion as to the quality of the title. (Titles which are found offfensive by some might be considered an exception.)
