Tim I don't understand your joke sentence cause I am not english.

You missunderstood my pb cause I was not enought accurate in my
description.


It is not foo1, foo2 to foo7 but

foo to change to bar
oof to change to rab
ofo to change to abr
fof to change to arb
etc...

all word are different


About variable or buffer, I don't search for conveniences but for good
response time of my script process.
I believed from a previous post that I had to avoid normal command or
exec 'norm' command and that storing data
into string was more efficient than using visual thing (into a buffer)
like moving or editing commands via normal or exec call
