Sat Dec 17 12:10:02 1994  Aubrey Jaffer  (jaffer@jacal)

	tables (which made copying of many tables impossible).

	* alistab.scm 
	(write-base): rewrote to not use pretty-print.

	* sc3.scm: removed (only contained last-pair, t, and nil).

	* Template.scm scheme48.init vscm.init (last-pair t nil): added.

	(chez:merge!): had a typo.

	of a <variable> did not include the <step> expression and the
	<test> expression, instead it incorrectly included the <init>
	expression. (rf. R4RS, 4.2.4)
	(hyg:tag-lambda): the body of a lambda expression should be
	generated using hyg:tag-generic instead of hyg:tag-vanilla. This
	allows expressions within lambda to behave hygienically.

Thu Mar  3 23:06:41 1994  Aubrey Jaffer  (jaffer@jacal)

	From: lutzeb@cs.tu-berlin.de (Dirk Lutzebaeck)
	* format.scm slib.texi: Format 3.0.
  * format's configuration is rearranged to fit only into SLIB. All
    implementation dependent configurations are done in the SLIB init files
  * format's output routines rely on call-with-output-string now if 
    output to a string is desired
  * The floating point formatting code (formatfl.scm) moved into
    format.scm so that there is only one source code file; this
    eliminates the configuration of the load path for the former
    formatfl.scm and the unspecified scope of the load primitive
  * floating point formatting doesn't use any floating point operation or
    procedure except number->string now; all formatting is now based
    solely on string, character and integer manipulations
  * major rewrite of the floating point formatting code; use global
    buffers now  
  * ~f,~e,~g, ~$ may use also number strings as an argument
  * ~r, ~:r, ~@r, ~:@r roman numeral, and ordinal and cardinal
    English number printing added (from dorai@cs.rice.edu)
  * ~a has now a working `colinc' parameter
  * ~t tabulate directive implemented
  * ~/ gives a tabulator character now (was ~T in version < 2.4)
  * ~& fresh line directive implemented
  * ~@d, ~@b, ~@o and ~@x now has the CL meaning (plus sign printed)
    automatic prefixing of radix representation is removed
  * ~i prints complex numbers as ~f~@fi with passed parameters
  * ~:c prints control characters like emacs (eg. ^C) and 8bit characters
    as an octal number
  * ~q gives information and copyright notice on this format implementation
    ~:q gives format:version 
  * case type of symbol conversion can now be forced (see
    format:symbol-case-conv in format.scm)
  * case type of the representation of internal objects can now be
    forced (see format:iobj-case-conv format.scm)
  * format error messages are now printed on the current error port
    if available by the implementation
  * format now accepts a number as a destination port; the output
    is then always directed to the current error port if available by
    the implementation
  * if format's destination is a string it is regarded as a format string now
    and output is the current output port; this is a contribution to
    Scheme->C to use format with the runtime system; the former semantics
    to append tothe destination string is given up  
  * obj->string syntax change and speedup
  * tested with scm4d, Elk 2.2, MIT Scheme 7.1, Scheme->C 01Nov91
