Hello,

I don't know whether format ever worked differently before in CHICKEN, but 
at the moment, the situation is as follows:

* The extras library unit contains a series of printf functions and an
  alias for sprintf, named format. The signature for this function
  corresponds to what is specified in SRFI-28 [1]:
    (format format-string [obj ...]) -> string
  Also the available selection of format control sequences in the
  format-string is very limited, just like the SRFI-28 says.

* There are two eggs for CHICKEN which provide more sophisticated format
  procedures compatible to the Common Lisp function: format and
  format-modular

* format-modular is the more modern and -- as the name says -- modular and
  extensible implementation of format.

* You can install both eggs in the usual way and they come with
  documentation of what they can do.


cu,
Thomas
