There are lots of ways to make comment in LaTex such as single percentage sign, \begin{comment} and so on, but as I know none of them use for creating comment for separating lines of a doc. It's good to know there is a way to make a group comment in LaTex.
ie:
we have text and command here and want to be comment(group1) . . . we have text and command here and want not to be comment(group2) . . . we have text and command here and want to be comment(group1) . . . we have text and command here and want not to be comment(group2) and other groups, now we want to comment one group and see result and then comment other group and uncomment first group and so on. for a bit challenging imagine that this groups of comment are distribute in multiple file (not all file but a part of it like one line in chapter 1, two lines in chapter 2, three lines in chapter 8 and ...).
any help would be appreciated.
commentpackage.comment. Did you know you can specify a different environment to be similar tocomment, likecommentA,commentB, ... That way you can switch them on/off as you need.\newif\ifstateA ,\newif\ifstateB and ... , \stateAtrue or \stateAfalse ... , \ifStateA ..... \fi. @TeXnician Its be good to have a general approach for this type of comments,better callssituational group comment.
