    History
    ~~~~~~~

    First, thank you for your bug reports, comments and suggestions.

    Thanks to the following people (in no particular order):
    (Sorry, if I have forgotten someone and for misspelled names).

    Gunther Nikl, Veli Nuutimäki, Eric Augustine, Laura Mahony,
    Marco Nelissen,  Jarkko Vatjus-Anttila, Yambo.

    V2.00
    o (An,Xn) is finally allowed in 68000/010 cpu mode.
    o tst lab was optimized to tst lab(pc) when only 68000/010 cpu was
      allowed.
    o Power ('^^') operator
    o EOR/XOR ('^') operator ended expression
    o Bitfield offset and width can now be defined after they use.
    o Various small bugs fixed
    o xdef and xref caused crash if operands had illegal chars.
    o Floating point numbers with exponent were incorrect.
    o FTENTOX was coded badly.
    o CNUL, DX and MOVE16 caused snma to guru when generating
      listing file.
    o When running out of mem, requester allows retry.
    o Memory usage for the end message (shell interface).
    o Pre-defined (commandline & optfile) symbols.
    o Macros with MEXIT and ENDC won't miss the ENDC.
    o Immediate data range checking can be turned off and it works
      for symbols which are declared after use.
    o Pre-assembled include files, which contain symbol and macro
      definitions of include files (was in V1.99 but I forget to
      mention it here). See INCLUDE and Arexx/MAKEGB docs.
    o ADDGB ARexx command lost main source file symbols after one
      INCLUDE operation. ADDGB is now a bit slower when there are many
      symbols, but it works as intended.
    o Bitfield stuff was broken in    V1.99.

    V1.99
    o Relative-relative (difference between labels) symbol was set as
      relative (ext_def) instead of correct ext_abs when xdef'ed.
    o Arexx startup now toggles snma on/off.
    o Some bugs from INCBIN removed.
    o "=" operator didn't produce FALSE (0) if the operands were not
      equal.
    o '040 stuff. MOVE16, CINV, CPUSH, MMU & FPU commands. Special regs.
    o Object file is no longer deleted if snma is trying to produce
      executable and there are errors and vice-versa.
    o Floating point equate file equates were screwed up as well as
      packed type conversion (nobody seems to use this :).
    o CASESEN=OFF caused xdefs to fail.
    o local symbols .l and .w were mixed up with long and word suffix,
      resulting enforcer hit and garbage expression.
    o Dcb directive works now like ds directive if it has only one
      parameter.
    o Lists with two successive commas are now handled (like x,,y).
    o Searches include files also from the directory where snma was
      started from (used to search only from where source file is).

    V1.97
    o Case-insensitive symbol names option.
    o ELSE directive works now.
    o Some new directives (types.i stuff mainly).
    o New expression handler (boolean operators).
    o IFs were tested even if assembly was toggled off.
    o Some errenous expressions - like (A)A -  don't crash anymore.
    o Multilevel optimizing.
    o Macro directive allows macro name as parameter.
    o DX directive (BSS to code or data hunk).
    o Absolute+Relative bug fixed (if in different hunks).
    o divu.l works (argh).
    o LINE DEBUG HUNK
    o Octal numbers.

    V1.95
    o ERRCOLOR keyword in template. Highlight error char.
    o AREXX/REMGB without parameters didn't work (+ fixed one mungwall hit
      from it).
    o QUIET startup switch disables only startup message. (You can redirect
      output to the nil: if you don't want any output).
    o SNMAOPT M controls now movem optimizing.(It was in Q flag).
    o End message is now little different in shell mode.
    o OPT directice changed to SNMAOPT to avoid any confusion.
    o fmovecr generated also extended immediate data.
    o Output file naming failed with ".s" extension (ooouups).
    o Behaves little better when running out of memory.
    o LABEL INCBIN <file>, LABEL get wrong value. (Veli Nuutimäki).
    o NULL byte in source ends it (to avoid to assemble binaries).
    o SELFCHECK arexx command.
    o Fmove.l #imm,fpcr works.
    o FBxx works now (Eric Augustine).
    o shift/rotate to <ea> generated spurious code.
    o INDEX register scale was allowed in 68000/010.
    o CNOP started to act like maniac if PC was more than 2^16.
    o addq/subq with undefined (at 1st pass) value, caused snma to begin
      'flying high again' actions. (Gunther Nikl).
    o "'" or '"'  works now (Gunther Nikl).
    o HUNK_RELOC32SHORT (implemented as 1015) to executables.
    o Produces also executables. (Laura Mahoney).
    o OPT A (address mode optimizing) was implemented as OPT E.
    o code_f, data_f, bss_f section types were not recognized.
    o FO, CLRFO, SETFO directives.
    o RS, RSRESET. RSSET directives (Marco Nelissen).
    o 'Old syntax' address mode had problems when base displacement had
       parenthesis around it.
    o Allows 99 macro parameters plus "<something>" parameters.


    V1.91
    o if any of cmpa operands had symbol which was relative or not defined
      in pass1, snma had serious problems.
    o If macro called another macro, \@ (unique label for one macro call)
      was different before the another macro call and after it.
    o Symbols which had only one char were not handled correctly.

    V1.90
    o moveq didn't allow xref'd data.
    o mc68xxx directives
    o Command line additions ([-option])
    o Object code naming now also checks ".s" and ".a" suffix.
    o OBJ filename in template was ignored (oh my).
    o tst with pc-relative was allowed on 68000 mode.
    o ext_ref symbols with same name were written many times, causing
      larger object file size (not actual code size).
    o xdef symbols were written to the all sections.
    o divu.l wasn't allowed.
    o Equates with relative components are handled better now.
    o Minimal WorkBench support
    o \*VALOF() + other macro 'insert functions'.
    o abslong to pc-relative optimizing.
    o DC generated too much data if the 2nd operand of the
      previous instruction was one which took some space.
    o REPT/ENDR directives
    o Global symbol table.
    o In cases where reloc was needed didn't create it, when
      symbol referred to equate which type was relative.
    o Equates with relative components are no longer written to
      the symbol list.
    o CHDIR (AREXX) command called FreeVec with wrong argument,
      causing memory loss (no crash, at least in my system).

    V1.70
    o BTST/BCHG/BSET/BCLR  Dn,<ea> set always <ea> as d0. (uups)
    o MOVEP didn't allow zero displacement.
    o ENDC switched assembly on sometimes when it shouldn't.

    V1.68
    o Some minor bug fixes and changes (okay, I forgot them).

    V1.65
    o Address components which started with 'Z' or 'z' were
      parsed to the totally wrong thing. (Bad one).
    o IFGT did unsigned test, instead of signed.
    o Didn't notice all cases when macro was already defined.
    o Include <devicename:filepath> didn't work.
    o Expression handler didn't catch all undefined symbols.
    o AREXX, SET command.
    o 'TST An' in 020+ mode wasn't allowed.
    o Destination address mode optimizing in move instruction
          generated spurious opcodes in some cases.
    o Movem->move optimizing.

    V1.60
    o AREXX PORT finally added
    o Several bugs fixed
    o LONGBRA flag to the template
    o ZAn no longer required if An omitted in addressing mode.


    ========================================================================

    Probaply I don't remember all the changes and fixed bugs, but I
    hope all the major ones are here.

    First released version of SNMA is 1.39.
