 YAEC 19a
 --------

1.9:

   6:th public release (Bugfix release)

   Well, last version had been pretty rearranged internally, it shows :)


   *** front-end ***

   - Fix : RAISE keyword had no effect.

   - Fix : oop was messed up.

   - Fix : conditional compilation did not work.

   - Fix : indexing buggy ...gaah..

   *** back-end ***

   - Fix : nilcheck/ptrcheck was messed up.

   *** linklib ***

   - Fix : stringformatting - now formats hexa correctly AND is
     even faster then before ! :)

   - Fix : StrAdd() with len did not set strlen correctly.

   - now libraries have exec,dos,intuition and graphics
     libraries opened automatically. (just as exes).

   - It is now possible to use WriteF(),PrintF(),PutFmt()
     from libraries!

   - Added new formatcode : \f  --  for floats !
     see example.

   *** source ***

   - Added debuglib.e and ddebuglib.e, modules with inline macros.
     You need the appropriate linklibs from AmigaŽ to use them.

   *** front-end ***

   - Implemented compiler-arg DEF/K.
     Define a globally visible symbol to be used with
     conditional compilation. ex : DEF DEBUG.
     (The global symbol YAEC is always defined)


1.8a: (July 15 2001)

   Fifth public release.

   *** front-end ***

   - Bugfixed : relative module path (*).

   - macros (#define) implemented.
     Bonus : 0-arg macros "()", "EXPORT #define" and "#undef" keyword.
     experimental : "IMPORT #define <label>"
       -> grab a #define from main-source into module.

   - conditional compilation (#ifdef,#ifndef,#endif) moved back in.
     bit of a fast hack but works for simpler stuff.

   - MACRO keyword -- expression substitution.
     The better way to do it. supports varargs! see docs for more info.

   *** back-end/linklib ***

   - dynamic strings/lists may have more than 32k elements.
     (theoretically 2 gig!) using 32bit currlen,maxlen
     (which is faster in 32bit memory)

   *** front-end ***

   - Constant "VARARGS" contains the latest number of variable
     arguments in MACRO.
     guess what this example does:
     MACRO FmtPrint(fmt,...) IS Stores(...) BUT (A0 := fmt) BUT \
                                (A1 := A7) BUT ASM " bsr PrintFmt" BUT \
                                Rems(VARARGS*4)
     bug : does not nest properly. (needs a stack..)

   - automatic "#define YAEC". useful with conditional compilation.

   - multiline RAISE statement.  (finally)

   - "EXPORT MODULE ..." well..guess what it does..  (alpha)

   - CONSTants now include static strings,lists,arrays,objects!
     ex : CONST MYVAL=10, MYSTRING='blabla',
                MYLIST=[1,2,-0.6, {func}, BLABLA],
                MYARRAY=[4,5,6,7]:INT               (beta)

   - Heheh... "MACRO" changed name again to "#macro".

   - Conditional compilation : #else keyword. (alpha)

   - Possible bugfix : Conditional compilation _may_ work 100% now :)

   - "<<" and ">>" accepted in constant expressions.
     ex : CONST BLA_F = 1 << BLA_B

   *** misc ***

   - wrote/added amigalib.e



1.7a: (June 15 2001)

   *** misc ***

   - some more sources in examples/ drawer.

   *** linklib ***

   - Bugfixed FastDispose(), some errors where introduced in prev version.

   - Bugfixed MidStr(), now copies 0 bytes if len=0.

   - Bugfixed SetStr(), didnt set nil-byte.

   - Bugfixed StrCopy(),MidStr(): now sets estring-len to 0 if copy-len is 0.


1.6a: (April 17 2001)

   *** Front-end ***

   - Speeded up module-parsing a little bit.

   - LONG/INT/CHAR didnt continiue on several lines. Fixed!

   - Well, one of the very last incompabilities just went away..
     MODULE 'alibrary' is now allowed ! :)

   - Disabled unification and lisp-cells as they are not really
     stable and bugfree. Positive : compiler got faster! :)

   - Disabled #define, #ifdef, #ifndef, #endif.
     (#define still gets parsed, but skipped)
     Yaec does not have a real pre-processor at the moment,
     but its planned. For now, a new keyword MACRO can
     be used instead of #define in many cases.
     ex : MACRO BLABLANAME IS 'blabla.library'
          MACRO Max(x,y) IS IF x > y THEN x ELSE y

     MACROs may be EXPORTed. (EXPORT MACRO ...)
     For more examples, look at the system-modules.

   - Changed syntax of single-line asm (ASM).
     Before : ASM <instruction>
     Now :    ASM '<whatever>' -> Note the apostrofes !
     Some advantages : 1. e-style comments can be appended.
                       2. Multiple ASM via BUT.

   - Completely got rid of EXTERN keyword and .ext files!
     The E language itself is now capable of doing all that
     and more. External defenitions are now in standard
     ascii module-format.

   - EXIT keyword implemented. (works with _all_ loop constructs)

   - relative module path (*) now works exactly as with EC.

   - multiple return values (3) implemented.

   - "EXPORT DEF ..." in modules is now allowed for compability.
     Preferred way is to type "IMPORT DEF ...".

   - Constant folding implemented.

   - Experimental error-recovery.

   *** Linklib ***

   - o FastNew(),FastDispose() now uses very fast recycling pool!
       (thanks to Wouter for helping here!)
     o Fix: FastNew() now raises "MEM" if out of memory.
     o Some NEW/END bugs removed.
     o Optimised NEW:s exceptiongenerating. (saved some instructions)

   - Startupcode would fail on > v40, when it should fail on < v40. Fixed.

   - Fix : Exes now returns exception as return-code. (if throwed out)

   - exe/lib/dev v39 support. not tested but hey!.. send me a line if it works.

   *** back-end ***

   - produces much better code now.

   *** Misc ***

   - bin/fdtool replaced with bin/fd2module.


1.5a:   (April 10 2001)

   Fourth public release.

   - ReadStr() didnt set stringlen correctly. does now.

   - Nested comments didnt work. Should now.

   - Amiga.lib working again :)

   - Added two .ext files : debuglib.ext and ddebuglib.ext
     for using debug.lib and ddebug.lib from AmigaŽ Dev CD.

   - Added bin/fdtool - convert Your .fd:s to .ext:s with this.

   - All the v40 standard Amiga librarybases are predefined now!

   - Stringformatting : added \z support. (zero-fill)

   - Globals now accept constants and simple constant expressions
     as defaultvalue. ex : DEF myglobal=ACONSTANT*4-7

   - FPU is now only required if floating point is used.
     (previous version required fpu anyway)

   - Added compiler args : WB/S,OPTI/S,HOLD/S,LARGE/S,SF=SHOWFILENAME/S.
     OPTI and LARGE does nothing for now, but may in future.

   - Default arguments to procedures works now.

   - PUBLIC/PRIVATE in OBJECT declaration works now.

   - Parameters to procedures where swapped. Fixed.

   - Librarymode now automatically creates .fd file.
     (use bin/fdtool to convert it to .ext)

   - Linkobject mode automatically creates .ext file.
     (still a bit experimental and under construction)

   - Fixed "IS" in "PROC name([params]) [OF name] IS <exp>".
     <exp> must be on the same line as "IS".

   - "OPT LINKOBJ" turned into "LINKOBJECT".
     (must be first thing in source (like LIBRARY)).

   - "*" preceeding module/extern-name now inserts path to
     the main-source. This is not perfect, but atleast makes
     things a little better.

   - Ptr-math is _allowed_ for now. (as in ec3.3a) Maybe it stays.
     Probably it will return, but a bit smarter; for example things
     like this should be spotted as errors, always :
     "array + array" or "ptr * 10" etc..

   - Added some missing internal functions : Mouse(), LeftMouse(),
     WaitLeftMouse(), RealF(), Rnd(), RndQ(), RealVal().

   - Multi-line DEF (DEF statement can continiue on several lines).

   - Modules can now be check-compiled.

   - OPT STACK implemented : OPT STACK=<sizevalue>
     -> manually set stacksize, overrides YAEC:s estimation.

   - Added keywords : JUMP and LAB.
     -> JUMP <labelname> : Jump to a local label.
     -> LAB <labelname>  : Define a local label.

   - Global labels (label:)

   - Global storage definition (LONG 1,2,3,.. / INT / CHAR)

   - Global Asm (ASM.. / ENDASM)


1.4a: (Feb 22 2001)

   Third public release.

   - Rewrote the hole type-system. Its real good now,
     and ready for the future.

   - NEW/END/++/-- fully implemented.

   - Added AFD-Copyright Notice.

   - YAEC is now SHAREWARE.

   - Fixed NILCHECK and added PTRCHECK cli-args.

   - Compiling LINKOBJ now automatically creates .ext file.
     (this means its usable now :))

   - LIBRARY/DEVICE mode ! (see examples)
     (device mode not tested)

   - Fixed a nasty bug in externs that could cause crashes
     in some executables.

   - Fixed arguments to procedures so they are evaluated
     in the same way they are on ec3.3a, that is from
     left to right! some programs should work beter now! :)

   - Fixed SELECT statement so it accepts "x OF y".

   - Amigalib support gone again.. :(


1.3b: (Jan 21 2001)

   - Added AmigaguideŽ documentation.

   - SetStdRast() was missing.

   - Enabled 68881/2 fpu-asm    (Martin Kuchinka)

   - Added Amigalib support. -> amigalib.ext

   - Improved NEW, objectptr[] still missing.

   - Added END keyword.
