Posts that include (pre) tags receive this caution (good!) with a ruler-line (sort of) in the red caution text.

It would make sense to reproduce the ruler line immediately above the text box, which appears below, in which I must make corrections (such as using the underscore continuation character), and through which I can scroll.

Here's my VBA code, and yes, it does have (pre) tags and yes, it ought have its lines split. I start to split, but feel the need to move the entire screen up to re-check the permissible length.

Perhaps a ruler placed where we are editing text would assist in producing standard-width postings?
