& center()
 
  Syntax: center(<string>,<width>[,<fill>])
 
  This function will center a string in a string <width> characters 
  wide, using <fil> characters for padding on either end of the string 
  for centering. If no fill character is specified then a space is 
  used. If <string> is longer than <width> characters, the string is 
  returned unmodified.
 
  Example:
 
  > say center(a,5,-)
  You say "--a--"
  > say center(*BAMF*,15)
  You say "    *BAMF*     "
