+

+Thu Apr 14 12:59:41 1994 Aubrey Jaffer (jaffer@jacal)
+
+ From: pegelow@moorea.uni-muenster.de (Ulrich Pegelow)
+ * mbe.scm (hyg:tag-do): Scoping was wrong. The region of binding
+ 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.
+ (hyg:tag-let): extended to support `named let'.
+
+Sun Apr 10 00:22:04 1994 Aubrey Jaffer (jaffer@jacal)

+
+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
+
+
