Not sure I understand your question very well...

My take on this...
Suppose you have two files test, test1.
I'd do a vi test* which will open test.
I'll make my changes and do a write.
Then go to escape mode and give a ":n" which takes me to the next file (test1 here).
I can edit this file and save the normal 'vi' way.
We can do this for many number of files (limit?? not sure buddy)
Hopefully this helps.
