      How does @StartUpCommonDir identify the folder to which it points? On my system, it points to "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup", while for another user who is testing my script, it points to "C:\Users\{USERNAME}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup", even though the other directory also exists on his system. Can someone please explain the built-in logic that leads to these different results? Thanks in advance.

      Here is the latest assembly engine from Tomasz Grysztar, flat assembler g as a dll which I compiled using original fasm engine. He doesn't have it compiled in the download package but it was as easy as compiling a exe in autoit if you ever have to do it yourself. Just open up the file in the fasm editor and press F5. 
      You can read about what makes fasmg different from the original fasm HERE if you want . The minimum you should understand is that this engine is bare bones by itself not capable of very much. The macro engine is the major difference and it uses macros for basically everything now including implementing the x86 instructions and formats. All of these macros are located within the include folder and you should keep that in its original form.  
      When I first got the dll compiled I couldn't get it to generate code in flat binary format. It was working but size of output was over 300 bytes no matter what the assembly code and could just tell it was outputting a different format than binary. Eventually I figured out that within the primary "include\win32ax.inc"', it executes a macro "format PE GUI 4.0" if x86 has not been defined. I underlined macro there because at first I (wasted shit loads of time because I) didn't realize it was a macro (adding a bunch of other includes) since in version 1 the statement "format binary" was a default if not specified and specifically means add nothing extra to the code. So long story short, the part that I was missing is including the cpu type and extensions from include\cpu folder. By default I add x64 type and SSE4 ext includes. Note that the x64 here is not about what mode we are running in, this is for what instructions your cpu supports. if you are running on some really old hardware that may need to be adjusted or if your on to more advanced instructions like the avx extensions, you may have to add those includes to your source. 
      Differences from previous dll function
      I like the error reporting much better in this one. With the last one we had a ton error codes and a variable return structure depending on what kind of error it had. I even had an example showing you what kind of an error would give you correct line numbers vs wouldn't. With this one the stdout is passed to the dll function and it simply prints the line/details it had a problem with to the console. The return value is the number of errors counted.
      It also handles its own memory needs automatically now . If the output region is not big enough it will virtualalloc a new one and virtualfree the previous.  
      Differences in Code
      Earlier this year I showed some examples of how to use the macros to make writing assembly a little more familiar. Almost all the same functionality exists here but there are a couple syntax sugar items gone and slight change in other areas. 
      Whats gone is FIX and PTR. Both syntax sugar that dont really matter. 
      A couple changes to structures as well but these are for the better. One is unnamed elements are allowed now, but if it does not have a name, you are not allowed to initialize those elements during creation because they can only be intialized via syntax name:value . Previously when you initialized the elements, you would do by specifying values in a comma seperated list using the specific order like value1,value2,etc, but this had a problem because it expected commas even when the elements were just padding for alignment so this works out better having to specify the name and no need for _FasmFixInit function. "<" and ">" are not longer used in the initializes ether.
      OLD: $sTag = 'byte x;short y;char sNote[13];long odd[5];word w;dword p;char ext[3];word finish' _(_FasmAu3StructDef('AU3TEST', $sTag));convert and add definition to source _(' tTest AU3TEST ' & _FasmFixInit('1,222,<"AutoItFASM",0>,<41,43,43,44,45>,6,7,"au3",12345', $sTag));create and initalize New: $sTag = 'byte x;short y;char sNote[13];long odd[5];word w;dword p;char ext[3];word finish' _(_fasmg_Au3StructDef('AU3TEST', $sTag)) ;convert and add definition to source _(' tTest AU3TEST x:11,y:22,sNote:"AutoItFASM",odd:41,odd+4:42,odd+8:43,w:6,p:7,ext:"au3",finish:12345');create and initalize Extra Includes
      I created a includeEx folder for the extra macros I wrote/found on the forums. Most of them are written by Thomaz so they may eventually end up in the standard library. 
      Edit: Theres only the one include folder now. All the default includes are in thier own folder within that folder and all the custom ones are top level.  
       Align.inc, Nop.inc, Listing.inc
      The Align and Nop macros work together to align the next statement to whatever boundary you specified and it uses multibyte nop codes to fill in the space. Filling the space with nop is the default but you can also specify a fill value if you want. Align.assume is another macro part of align.inc that can be used to set tell the engine that a certain starting point is assumed to be at a certain boundary alignment and it will do its align calculations based on that value. 
      Listing is a macro great for seeing where and what opcodes are getting generated from each line of assembly code.  Below is an example of the source and output you would see printed to the console during the assembly. I picked this slightly longer example because it best shows use of align, nop, and then the use of listing to verify the align/nop code. Nop codes are instructions that do nothing and one use of them is to insert nop's as space fillers when you want a certian portion of your code to land on a specific boundary offset. I dont know all the best practices here with that (if you do please post!) but its a type of optimization for the cpu.  Because of its nature of doing nothing, I cant just run the code and confirm its correct because it didnt crash. I need to look at what opcodes the actual align statements made and listing made that easy.

      procf and forcea macros
      In my previous post I spoke about the force macro and why the need for it. I added two more macros (procf and forcea) that combine the two and also sets align.assume to the same function. As clarified in the previous post, you should only have to use these macros for the first procedure being defined (since nothing calls that procedure). And since its the first function, it should be the starting memory address which is a good place to initially set the align.assume address to. 
      Attached package should include everything needed and has all the previous examples I posted updated. Let me know if I missed something or you have any issues running the examples and thanks for looking
      Update 04/19/2020:
      A couple new macros added. I also got rid of the IncludeEx folder and just made one include folder that has the default include folder within it and all others top level.
      dllstruct macro does the same thing as _fasmg_Au3StructDef(). You can use either one; they both use the macro.
      getmempos macro does the delta trick I showed below using anonymous labels. 
      stdcallw and invokew macros will push any parameters that are raw (quoted) strings as wide characters
      Ifex include file gives .if .ifelse .while .until  the ability to use stdcall/invoke/etc inline. So if you had a function called "_add" you could do .if stdcall(_add,5,5) = 10. All this basically does in the background is perform the stdcall and then replaces the comparison with eax and passes it on to the original default macros, but is super helpful for cleaning up code and took a ton of time learning the macro language to get in place. 
      Update 05/19/2020:
      Added fastcallw that does same as stdcallw only
      Added fastcall support for Ifex
      Corrected missing include file include\macro\if.inc within win64au3.inc

      Here is an old goodie from ms demonstrating concepts behind multithreading and using mutexes to control sharing the screen. Its unfortunately just a console application so you have to press compile (f7) to run (can get annoying if you want to play with the code) but still pretty cool :). Each little question mark box (could be any character (used to be a smiley face in win 7)) is its own thread keeping track of its own coordinates. Each thread shares the screenmutex by kinda waiting in line for ownership of it. When the thread gains control it updates the screen, then releases the mutex for the next thread. 

      First I wrote it in pure autoit to confirm all working as expected. The Console functions actually threw me for a loop. They actual want the whole value of the coord structs and not a ptr to it so that "struct" without a * was a little uncommon. Below au3 code is just the lonely cell bouncing around.
      Func _BounceAU3() ;set a random starting id. we use this to rotate the colors Local $iMyID = Random(1, 15, 1) Local $tMyCell = DllStructCreate('char mc'), $tOldCell = DllStructCreate('char oc') Local $tMyAttrib = DllStructCreate('word ma'), $tOldAttrib = DllStructCreate('word oa') Local $tCoords = DllStructCreate($tagCOORD), $tOld = DllStructCreate($tagCOORD) Local $tDelta = DllStructCreate($tagCOORD) ;Random start and delta values $tCoords.X = Random(0, 119, 1) $tCoords.Y = Random(0, 29, 1) $tDelta.X = Random(-3, 3, 1) $tDelta.Y = Random(-3, 3, 1) ;set character/cell attributes $tMyCell.mc = $iMyID > 16 ? 0x01 : 0x02 ; doesnt seem to make a differnce in windows 10 $tMyAttrib.ma = BitAND($iMyID, 0x0F) ; Set the character color Do ;check the last position values DllCall('kernel32.dll', "bool", "ReadConsoleOutputCharacter", "handle", $g_hStdHandle, "struct*", $tOldCell, "dword", 1, "struct", $tOld, "dword*", 0) DllCall('kernel32.dll', "bool", "ReadConsoleOutputAttribute", "handle", $g_hStdHandle, "struct*", $tOldAttrib, "dword", 1, "struct", $tOld, "dword*", 0) ;if the last postion was this cell, blank/empty the cell. (Otherwise its been taken over by another thread) If ($tOldCell.oc = $tMyCell.mc) And ($tOldAttrib.oa = $tMyAttrib.ma) Then DllCall('kernel32.dll', "bool", "WriteConsoleOutputCharacter", "handle", $g_hStdHandle, "byte*", 0x20, "dword", 1, "struct", $tOld, "dword*", 0) EndIf ;write the current cell DllCall('kernel32.dll', "bool", "WriteConsoleOutputCharacter", "handle", $g_hStdHandle, "struct*", $tMyCell, "dword", 1, "struct", $tCoords, "dword*", 0) DllCall('kernel32.dll', "bool", "WriteConsoleOutputAttribute", "handle", $g_hStdHandle, "struct*", $tMyAttrib, "dword", 1, "struct", $tCoords, "dword*", 0) ;update coords $tOld.X = $tCoords.X $tOld.Y = $tCoords.Y $tCoords.X += $tDelta.X $tCoords.Y += $tDelta.Y ;change directions if we are out of bounds If $tCoords.X < 0 Or $tCoords.X >= 120 Then $tDelta.X *= -1 If $tCoords.Y < 0 Or $tCoords.Y >= 30 Then $tDelta.Y *= -1 Sleep(75) Until GUIGetMsg() = -3 EndFunc ;==>_BounceAU3  
      From there the that function converted into assembly so we can call as a thread. The only real differences are the extra parameters we passing as a structure and I also generate the random starting values in autoit instead, then pass them to the function. Here is what the main assembly function looks like. I added comments for each peice of code from au3 that we are translating:

      Heres a function for searching for a bitmap within another bitmap. The heart of it is written assembly (source included) and working pretty quick I feel. I have included an example which is pretty basic and should be easily enough for anyone to get the concept. 
      You will be given a small blue window that will take a screencapture of that size:

      It will then take a full screenshot and highlight all locations that it found
