It was rough and crude, and since I couldn't get it to assemble, I couldn't begin to debug it.

Here it is:

A few things that I don't like:
1. the randInt... in Nasm it seems I can use the rdtsc directive, but it flags an error in MASM: error A2085:instruction or register not accepted in current CPU mode, so it works well in Nasm on linux, but using GetTickCount, no so well.
2. I would like to implement it as a MACRO, like the rv example, where I have Map(parameters).
3. It appears that in Nasm I can input a mnemonic as a parameter into a macro, can anything be done like that in Masm?  for example... Map(mnemonic, map_operand, array, length)?

Code: [Select]
include /masm32/include/masm32rt.inc

map MACRO arg1, arg2, arg3, arg4:VARARG
FOR var, <arg4>
.if var == "m"
xor eax, eax

if you use ".586" or ".686", you should be able to use RDTSC

.... or, you could hardcode it as
Code: [Select]
  DW 310Fhor
Code: [Select]
  DB 0Fh,31h

Here is a skeleton for the macro. Usage: mov eax, map("m", op, offset num_array, array_len)

Code: [Select]
map MACRO arg1, arg2, arg3, arg4
Local tmp$
  ifidn <arg1>, <"m">
; echos appear in the output window
echo Yeah, it's the "m"
mov esi, arg2
mov edi, arg3
mov ecx, arg4
; ... more code ...
  else
tmp$ CATSTR <Your first arg is >, <arg1>, < - whatever that means>
% echo tmp$
  endif
  exitm <eax>
ENDM

Great!!!

Since I am using the MASM32 include of masm32rt.inc, and it was coded with a .486... I changed it to .686, and I'll be hornswaggled!

Bless ya, my snail.  :lol:

I now have my original and better random number generator back.  :t

I EDITED the above post with the 2nd code block to reflect updates.

Go the whole hog.
Code: [Select]
.686p
.mmx
.xmm
These size restrictions go back to the days when you could not run early Pentium code on an 8086. Turn everything on and you have escaped the old stuff.

Yes, as initially suggested. Please add CPU detection to your code for production releases
to ensure run-time compatibility - if you use strange and wonderful instructions. On another
topic : macros. As pointed out by jj2007 and hutch the MASM32 library and macro calls typically
do not add significant cycles to your code [after-all the code is refactored to be extremely speedy
over years of use, by many many forum members and tireless hutch]
MASM = MacroASseMbler [it's in the name  :icon_eek:] macro's are just short hand notation for
code-lets. Thus produce the same processing cycles as the long-hand versions. They are convenient
and produce more readable/maintainable/consistent code.  But it's always a good idea to research
what exactly they do under the hood as to avoid register thrashing or unpredictable results.
Are you pondering what I'm pondering? It's time to take over the world ! - let's use ASSEMBLY...

Okey dokey,

I am pretty much done with this assignment.

I am still working on the MACRO part.

This finally turned out decent.

TO: I was unsure about that rv macro, but that thing is cool, when I did the mov handle, rv(GetStdHandle, STDOUT), in there.

I have learned to embrace INVOKE for speed and brevity.

It took me a long time to figure out why the first index[0] was coming back with what I thought was garbage, but it was the pointer to the array... got that solved.

It works fine but your map macro is not being used and not operational. See my reply#32 above, you may have missed it.

Since I am using the MASM32 include of masm32rt.inc, and it was coded with a .486... I changed it to .686....

it's not a good idea to alter the library file that way
now, when you post code that has "INCLUDE \masm32\include\masm32rt.inc",
other programmers will not be compatible

the CPU selection directive may be reassigned without a "duplicate" error
instead, do it like this...

Code: [Select]
INCLUDE \masm32\include\masm32rt.inc
.586

i start writing programs by using a template program
it starts like this

Code: [Select]
        .XCREF
        .NoList
        INCLUDE    \Masm32\Include\Masm32rt.inc
        .686p
        .MMX
        .XMM
        .List

also, RDTSC is not the only instruction like this
the same applies to using the CPUID instruction

Yes, this MACRO is a work in progress, I will work on this part now.

i start writing programs by using a template program
it starts like this

Code: [Select]

        .XCREF
        .NoList
        INCLUDE    \Masm32\Include\Masm32rt.inc
        .686p
        .MMX
        .XMM
        .List


also, RDTSC is not the only instruction like this
the same applies to using the CPUID instruction

I made those updates above.

An update to the update:

I finished the map MACRO: works just like the map PROC:

now I can do either:
mov array, rv(map, <parameters>)

OR

mov array, map(<parameters>)

I like the latter due to it looking more like Ruby or Python...  :eusa_naughty:

Code: [Select]
map MACRO var:REQ, arg2, arg3, arg4
.if var == "m"
xor eax, eax
xor esi, esi
xor ecx, ecx
mov ecx, arg4 ; len
mov edi, arg2 ; array
L1:
mov edx, DWORD PTR [edi+esi]
mov eax, arg3 ; operator
mul edx
mov [edi+esi], eax
add esi, TYPE DWORD
loop L1
jmp _DONE
.elseif var == "a"
xor eax, eax
xor esi, esi
xor ecx, ecx
mov ecx, arg4
mov edi, arg2
L2:
mov eax, arg3
add eax, DWORD PTR [edi+esi]
mov [edi+esi], eax
add esi, TYPE DWORD
loop L2
jmp _DONE
.elseif var == "s"
xor eax, eax
xor esi, esi
xor ecx, ecx
mov ecx, arg4
mov edi, arg2
L3:
mov edx, DWORD PTR [edi+esi]
mov eax, arg3
sub edx, eax
xchg edx, eax
mov DWORD PTR [edi+esi], eax
add esi, TYPE DWORD

jmp _DONE
.elseif var == "d"
xor eax, eax
xor esi, esi
xor ecx, ecx
mov ecx, arg4
mov edi, arg2
L4:
mov eax, DWORD PTR [edi+esi]
xor edx, edx
cdq
idiv arg3 ; 3dcccccd
mov [edi+esi], eax
add esi, TYPE DWORD
loop L4
jmp _DONE
.endif
_DONE:
mov eax, DWORD PTR [edi]
    EXITM <eax>                          ;; EAX as the return value
ENDM

I have one more question:

Can we pass an actual mnemonic as a parameter in a macro?

It appears that it is possible in NASM.

i.e.
%macro map 4 (args count)
    // code here
   %1 eax, 4  // where mul, div, add, sub would replace the %1
   // rest of code
%endmacro

so a macro definition call would be like:

map(mul, <parameters>) in MASM

???

Yep  :t

I have to refactor the macro now, as I try to differentiate between the different mnemonics instead of char literals.

@Hutch

I've been poking around the Masm32 includes and macros, reading help and MSDN docs... then using Select-String codelet in Powershell to find if the function or macro is available in MASM32.  I think that it has a 99% positive hit count, anything that didn't hit, I am adding.  Usually it's just small macros or defines... for example, I added the UNREFERENCED_PARAMETER macro, MSDN uses it a lot, not really neccessary, but it's an elegant way to stop the assembly warnings of unused parameter variable.

UNREFERENCED_PARAMETER MACRO param:REQ
   mov param, 0
ENDM

Code: [Select]
UNREFERENCED_PARAMETER(lpParam)

Anyways
Thanks

I am not sure how you are using this macro but you can use :VARARG in macros if a variable argument count is required.

I find the Visual C++ unreferenced_parameter macro in a lot of MSDN examples.

BTW, I am curious to what the REQ means?  I see it a lot, and it seems to be used as a delimiter for the ( ) brackets?  But it's not in the MASM >= 14.0 docs, and I haven't found any full explanation for it yet.
