Place the following script in your ~/bin subdirectory.  Name it 'center'.
Then execute it from within your vi session as follows:
	:m,n ! awk -f ~/bin/center
where m is the beginning line number and n the ending line number of the lines
you want centered within the file.  Note, this is not my code.  I got it from
a friend some time ago.  I don't know who originated it, but it works:

#
{ for (i = 1; i < (80 - length($0)) / 2; i++)
   printf("%s"," ")  
  print $0 }
