New features in CGOL 74.  Please report any bugs to MJF;.

[1]  The lexical syntax has been cleaned up a little.  An altmode
     may be included in a character string or in a comment by
     preceeding it with the escape character "?".  An unprotected
     altmode now causes an error.  To put a quote character (")
     into a character string, it must be doubled.

[2]  CGOLREAD now takes an argument which is treated just like
     the argument to READ.  Namely, if CGOLREAD encounters an end-of-file
     as the first thing upon being called, the argument is returned;
     otherwise it is assumed that there follows a complete CGOL
     expression followed by the input terminator (an altmode or dollar).
     If not, an error is reported.  If the argument is NIL, then
     initial end-of-files are passed over.  Sometime in the future,
     the argument may become optional, but for now it is required.

[3]  The necessary changes for compatibility with [2] have been made
     in MAKLISP.

[4]  A new bracketing operator "OCT" allows the reading of a
     portion of CGOL text with IBASE=8 so numbers are read in octal
     (unless followed by a dot).  The following text MUST be
     enclosed in parentheses. E.g.  oct(12) $ prints 10., and
     oct(12+14) prints 22.

[5]  Tokens may now be composed of multiple characters.  NEWTOK "foo" defines
     the string foo to be a token.  It may then be used like any
     other token, e.g. appear in infix, prefix, and define statements,
     be used as a variable, etc.  There are two points of caution.
     (i)  The only characters which may appear as the FIRST character
     of such a token are special characters other than quote ("),
     percent (%), exclamation (!), dollar, altmode, and question mark (?).
     (ii)  Every prefix of a multiple character token also becomes
     a token.  Thus, defining NEWTOK "*-*" causes 2*-3 to parse
     incorrectly.  Of course, 2* -3 will still work all right.

[6]  New bit-vector operators have been defined using the multiple
     character token feature described above.  They are:
	.N.  -  complement;
	.A.  -  logical and;
	.V.  -  logical or;
	.X.  -  exclusive or;
	.^.  -  left shift.

[7]  The current version of CGOL may be fasloaded from COM: CGOL FASL.
     Two other ways of invoking it are:  (i)  Type
     (CGOL) or (CGOLREAD) at LISP (they have autoload
     properties);  or (ii) Type :L CGOL;  when you start
     your LISP.
