If I put a line of text and then say 10 blank lines and another line of text, vi refuses to delete the blank lines. I tried using x (while not in insert mode) and they don't go away. Then I switched to insert mode and tried delete and backspace keys and I cannot get rid of the blanks lines.


I've been using vi and vim with Linux and Solaris for decades and never been able to delete lines either of those ways. x only deletes characters under the cursor, backspace and delete only delete characters on the current line that have been typed since entering edit mode. Once edit mode is exited, delete and backspace won't erase any previous characters.

I always use dd to delete individual lines, for multiple lines set a mark (ma) at the first line to delete, move to the last line to delete a do d'a (delete from current line to line marked "a"). There are many other uses of d for deleting also.


Solid advice.

I have noted that vim appears (in some versions at least, I've mostly been using it on RHEL 6 lately) that it will actually backspace over things that were not entered in the current input session, while you're in input mode, and will backspace through newlines as well, which is different from the standard old-school vi behavior. But I don't know whether you have to do something (that perhaps Red Hat does by default) to enable that behavior.

I bought a new Cyclone 5 Platform for my project. It has the ability to also include ARM functions, eg for MIDI.

And : C5 has so much power and resources for programming Smile

Very similar, although they look like they're >$100US more per board.
