Also: MetaL@ a start on a wierd little cross-processor bnf translation language.

Getting started? Follow these steps

1. Go to Hutch's site http://www.movsd.com/ and get MASM32 (MASM specific) and the Iczelion tutorials for MASM32

   This is the NEXT STEP in rapid assembler code development, Version 4 has its own code generator to create basic front ends in less than a minute, it has it own extendable library with full source code for efficient modular code design, it includes WINDOWS.INC version 1.12 that Iczelion has just upgraded and MASM32.HLP has a new section for pentium optimisation from an anonymous author on the net as well as the reference for the procedures contained in MASM32.LIB.

   This version has its own LIB.EXE, DUMPBIN.EXE and EDITBIN.EXE with source code so that the full capacity of LINK.EXE can be realised. Clive Turvey has given permission to include his latest version of DUMPPE.EXE with MASM32v4 which is set up to disassemble your EXE file directly from the editor. All you need to do is unzip DUMPPE.ZIP in the BIN directory.

2. Get the WinDbg debugger.

   Read the help file, play around, setup a workspace do all the tutorials from MASM32.

3. Read all the back issues of ASM Journal and its message forum leaving the non-32 bit and *nux stuff behind.
   
4. If you still have questions, go to http://win32asm.cjb.net (or http://203.157.250.93/win32asm/ or http://www.hutch.ukshells.co.uk/iczelion/) Iczelion's Win32 Assembly HomePage The Official HomePage of #win32asm: Tutorials, basics, VxD, direct draw, winsock, links to everywhere. Then post a message on The message forum for Win32Asm Programming or to the eGroups forum at http://www.egroups.com/group/win32asm/

• WALK32 This programming toolkit is designed for the experienced ASM programmer who not only wants to casually write some assembly code, but instead aims at building large projects in all assembly language.
• Clive's Windows Source http://www.tbcnet.com/~clive/vcomwinp.html Windows Source version 3 works with V Communications' Sourcer, version 6.51 and later, to produce commented disassemblies of Windows 16 & 32 bit executables, dynamic link libraries (DLLs), device drivers, and 32-bit virtual device drivers (VxDs).

• http://www.programmersheaven.com/zone5/index.htm Code, tools, librarys, etc...

Tricks:

• in a batch file, you can do ;@<command> and MASM will ignore the line but the command line (don't say DOS) interpreter will excecute the command. One file can be the source code and make batch file. First line is ;@GOTO :MAKE if you want the make batch at the end.

Questions:

• wadr at spamadinet.com.uy asks:

  Can someone help me width this code :
  
  void __inline * memcpy(void *dest, const void *src, size_t size) {
  bprintf("memcpy(0x%x,0x%x,0x%x);\n",dest,src,size);
  __asm__ (
  " push %%esi \n"
  " push %%edi \n"
  " push %%ecx \n"
  " mov %0, %%esi \n"
  " mov %1, %%edi \n"
  " mov %2, %%ecx \n"
  " push %%ecx \n"
  " shr $2, %%ecx \n"
  " rep movsl \n"
  " pop %%ecx \n"
  " and $3, %%ecx \n"
  " rep movsb \n"
  " pop %%ecx \n"
  " pop %%edi \n"
  " pop %%esi \n"
  : : "S" (src), "D" (dest), "c" (size)
  );
  return dest;
  }
  
  I never saw before a inline assembly wrote in that way. ( width %, $, \n and between "" )
  and i specially can´t understand this
  : : "S" (src), "D" (dest), "c" (size)
  
  thanks a lot
  

  it is assembly using Visual C+++

Comments:

• With the src coming before the dest and the $ preceding immediate values and the % in front of registers it looks like assembly code int AT&T asm language syntax+

  Ref: http://www.sxlist.com/techref/language/asm/win32asm.htm
  
  The link in paragraph 4 "Microsoft Win32 API online documentation..."
  http://msdn.microsoft.com/isapi/msdnlib.idc?theURL=/library/psdk/psdkref/alphafunc_3bjm.htm
  is incorrect.
  
  The new WIN32 API URL is
  http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winprog/winprog/windows_api_reference.asp
