The same problems occurred in a previous HP-UX version of 'vi' and I reported the bug. Now, the bug is fixed and even after an excursion via a :map! command, the INSERT-mode anunciator will be there in the left hand lower corner if you are in insert mode. Similarly, there were problems with the early HP-UX 'vi' INSERT mode anunciator if you inserted so much new text in one line that you wrapped around onto a new line, in which case the INSERT MODE (erroneously) got switched off. This bug has also been fixed by HP. The only remaining problem with these showmode anunciators is that, in contrast to all other 'vi'/'ex' messages, they are not accessible through the Native Language System message catalog. So even if all other messages in 'vi' in our case are written in Swedish, the showmode anunicators are still in English. This is a bit confusing for secretaries who use 'vi' as a Swedish language word processor system, but I hope HP will fix that problem soon. By the way, the ":set novice" command cannot be executed within 'vi' proper. However, it will be set if you invoke the editor as 'vedit' instead of 'vi'. Then you will run 'vi' in a beginner's mode (shomwode on, no magic characters, report = 1 etc).
