Version 1.3 implements a new internal design for arrays. See file
CHANGES.

Version 1.2.2 is best for MsDOS
---------------------------------------------------------

Changes from version 1.1.4 to 1.2:

1) Limit on code size set by #define in sizes.h is gone.

2) A number of obscure bugs have been fixed such as,
   you can now make a recursive function call inside a for( i in A) loop.
   Function calls with array parameters in loop expressions sometimes
   generated erroneous internal code.

See RCS log comments in code for details.

Reported bugs are fixed.

3) new -W options

-We file   :  reads commands from file and next argument, regardless
	      of form, is ARGV[1].  Useful  for passing -v , -f etc to
	      an awk program started with #!/.../mawk

#!/usr/local/bin/mawk -We

myprogram -v   works, while

#!/usr/local/bin/mawk -f

myprogram -v    gives error message
	  mawk: option -v lacks argument

This is really a posix bozo.  Posix says you end arguments with
      -- , but this doesn't work with the #! convention.

-W interactive :  forces stdout to be unbuffered and stdin to
	be line buffered.  Records from stdin are lines regardless of
	the value of RS.  Useful for interaction with a mawk on a pipe.

-W dump, -Wd   :  disassembles internal code to stdout (used to be
       stderr) and exits 0.

4)  FS = "" causes each record to be broken into characters and placed
     into $1,$2 ...

same with split(x,A,"") and split(x,A,//)

5)  print > "/dev/stdout"  writes to stdout, exactly the same as
    print
    
    This is useful for passing stdout to

function my_special_output_routine(s, file)
    {
	# do something fancy with s 
	print s > file
    }

6) New built-in function fflush() -- copied from the lastest att awk.

fflush() : flushes stdout  and returns 0
      fflush(file)  flushes file and returns 0; if file was not an
      open output file then returns -1.

7)  delete  A ;  -- removes all elements of the array A

intended to replace:

for( i in A) delete A[i]

8)  mawk errors such as compilation failure, file open failure, etc.
    now exit 2 which reserves exit 1 for the user.

9)  No program now silently exits 0, prior behavior was to exit 2 with
    an error message
