> ~ How to select lines of length  40 while in vi?

Use vi to filter your file thru awk.  You can write an
awk script which marks the lines you want to treat.
Here is an example:
1G							#start at line 1
!Gawk ' {if (length > 40) {print "mark"$0} else print}'	#filter file thru awk
g/mark/cmds						#do your thing

The unique power of UNIX (UPOU) is that vi includes awk. All tools are
designed to be included in all other tools.
