Ok! Thanks.

but if i check the global environment with another process the variable X is not incremented. Why?
How I can increment a variable over process?

Hi to all, I return on this forum after a long time and i not remember how work the dos batch... I use a macro recorder that have a possibility ok run an external command like CMD.EXE or OTHER I need to use a variable and I need to increment this variable. I have probed with setx x 2 cmd.exe /v:on /...

Hi Icarus, very nice work!
This is very fast color graphics

Hey, I wanted to share something I made last night. I thought maybe this would be useful FIXED! Accuracy is 100% https://gyazo.com/1765c4579c80f2688789b12901d762ad.png @echo off & setlocal enableDelayedExpansion for /l %%a in (1,1,20) do ( set /a "rnd1=!random! %% 49 + 1", "rnd2=!random! %% 49 + 1"...

Sorry to dig this up, but I've found use out of this. I was also wondering if it were possible to create a POW macro such as this? Thanks in advanced!! the pow function is reconducible to log function and exp function. pow( x, y ) => exp( y * log( x ) ) I will try to attemp using this article https...

The new windows version 10 include more color using VT100 escape sequences The code iterate in HSL colors and convert to RGB and put a color char using escape sequence this code show more colors, use raster fonts 4x6 to get in full screen @echo off & setlocal enabledelayedexpansion mode 260,92 for /...

Hi Icarus,

This is great result!!!

You could do something like this: :start if current_time more than 09:00 then notepad.exe wait 1 minute (or wait 24 hours) goto start Saso this? @echo off :label ping 127.0.0.1 -n 2 >nul if %time:~0,2% equ 9 if %time:~3,2% equ 0 ( start notepad.exe ping 127.0.0.1 -n 86398 >nul ) goto label einstein...

I have done the above optimizzation The new gain is about 15% or more for big NumQuads. time is in seconds http://i66.tinypic.com/2czcx14.png the new version include, if defined pidebug variable, print on title with current time and percent achieved. It sync the timer at 00 second before start for e...

I thinks that next step is using multi-thread creating a pipeline... But in the middle there is an optimization in the block of division: AR_Recip/N AR_Recip/N => AR_Recip/(N*N) But this can have an overflow if N*N > 214747 For formulas : Pi = 48*arctan(1/18) + 32*arctan(1/57) - 20*arctan(1/239) and...

I have probed to tuning for best performance the version 4. There are few things to do but I have tried and I have done the follow: - The SET/A is faster if use costant then I have removed the variable @ - Remove unused variables, move at bottom of environment less used variables. N_FORMULA->_FORMUL...

I have compared the last version of mine and your and the original

Hi Antonio, this version is very efficiency. There is a problem when I press CONTROL-C, the batch don't stop. It's possible break ? Francesco EDIT set /A A_NumGroups = 3 set /A A_NumQuads = NumGroups*25, A_MaxQuadIndex = A_NumQuads-1, @ = 10000 There is an error on A_NumQuads. It uses NumGroup inst...

I have just realized that SET/P is slower than FOR/F this version substitute the precedent. The break even point (BEP) is passed from about 500 NumQuads to about 400 NumQuads. http://i63.tinypic.com/qswo6a.png the new code: @if defined talk (echo on) else (echo off) setlocal EnableDelayedExpansion e...
