This is the changes file, that explains what has changed over the
revisions: current revision "2.0"

1.0 -  Original <released but never really spreaded>

1.1 -  Changed a lot of  for( ... < ...) into   for( ... != ...)
       Corrected a hilarious bug in err_undefs. (Missing { }). How
       did NASM65 ever work without those ??
       Added noisy tokenizer for TOS version.   (Nat!/1991)

-- INBETWEEN --  <start>
1.0:-  Patch for bug that was intermittently corrected in 1.1 (Nat!/1991)
   ^-----{ NOTE!
-- INBETWEEN --  <end>

1.1 -  Improved int_suckin a bit. Also directive_suckin.

1.2 -  Deimproved some code, made it MSDOS portable. Heavy optimization
       work did strangely enough not pay off anywhere (don't ask me why)
       on paper it looked quite substantial.
       Streamlined I/O further, fixed some bugs in support programs.
       Now forward branches that go over the top give at least a hint,
       where the branch might have been (doesn't work well with macros
       includes and the like).

2.0    Argh! This is already v2.0, a few additions I needed to incorporate
       to 'effortlessly' assemble FTOE (my own gigantic game (har har))
       unfortunately forced a major redesign in the object module
       structure. .DS now creates holes in the binary instead of
       just dropping zeroes. For Display lists and other stuff which
       should lie on page boundaries an -a option has been added.
       (Sorry no GC yet -> 3.0). Some code has been de-inlined to get the
       assembler to a targeted < 50K. More bugfixes than I hoped would
       be neccessary (probably added quite a lot with this version).
       A selection:
         Numerous bugs and improvements in support programs
         more_space   -- only worked for two segments
         clean_labels -- did not clean labels

Made the assembler much more usable by countless bug fixes and
improvements.

            FOR A REAL RELEASE, VERSION WILL BE SET BACK TO 1.0

1.0   UNIX portability apparently achieved. Looks good right now.

16.Jan.1992:           Added ARGV support via PCVSTART.O, made AMIGA 
                       compatibilty changes thanx to dinadan@mcshh.hanse.de
NASM65   v1.6          Fixed a typing error in code.h for PHILOSOPHICAL
NLINK65  v1.4          code. Fixed filename extension memory clobber bug
NLIB65   v1.2          Object files made prettier a bit. Dinadan fixed two
DISASM65 v1.7          bugs (one each) in XTRCTBIN & CHKFFFF. Fixed one bug
XTRCTBIN v1.1          in MD_SUCK (for 680[234]0 machinery)
DEMAC65  v1.4          XTRCTBIN now (hopefully) converts Atari binaries into
CHKFFFF  v1.1          C64 & AppleII binaries. UNIX portablity achieved
                       yet once again (har har). Cut filenames in error
                       messages. Added C64 and AppleII to disassembler.
                       
---------------------------------------------------------------------------
18.Sep.1992:           Fixed 'date' bug in "changes.txt" for last rev. (har)
                       Fixed two really atrocious bugs.
                       Fixed one lame (but TOUGH to trace down) nfree()
                       bug.
                       To remain compatible with some bogus 32-bit                        
NASM65   v2.0          compilers, I needed to incorporate a change in the
NLINK65  v2.0          filestructure. This means that the object files go
NLIB65   v2.0          downwards incompatible from now on!! This also gave
DISASM65 v1.8          me the chance to increase the identifier length in
XTRCTBIN v1.2          the object table to 32 characters. You PASCAL-
DEMAC65  v1.5          like coders, can now write (and link)
CHKFFFF  v1.2          THIS_VARIABLE_COUNTS_MICE   .byte 2 
CRLF155  v1.7          THIS_VARIABLE_COUNTS_SHEEP  .byte 234

(It should be possible, that) old objects can be extracted from libraries, 
but old objects can not be added. Due to an error in the library code, 
libraries generated on INTEL (BIGENDIAN) machinery were never compatible. 
This has been fixed. 
Unfortunately for those users downward compatibility has been lost!

Made a full hearted attempt at providing PC compatibility. Since that 
system sucks even more than previously suspected, I can't make any 
guarantees about stability. As soon as the PC goes to 32-bit, this should 
work just dandy. My once beautiful source has been now littered with 
'huge' pointers, ridiculous casts and other kludgey stuff.

Again to the port to MSDOS. Everything seems to work except the damned
linker. TC3.0 couldn't deal with huge pointers correctly and TC2.0 (I 
dunno) code chokes somewhere, sometime unpredictably. I think this is
fixed now with the nfree() fix.
