I add this variant made by T3rror, because it introduces intelligent ideas without losing speed. Indeed it should be faster because it supposes the non -existence of double quotes around the variables Hi Einst - I was looking over the final StrLen macro version you posted on dostips and noticed an e...

Thanks for the detailed and understandable explanation of escaping double quotes.

The rewritten code with spaces is a really good idea; I'll keep it in mind.

Yes, what Antonio mentioned was used in that thread testing the performance of the set command, and in some cases there was a difference. In the meantime, I added the limit to 8191. It lost a bit in the lower range, but I don't understand why; further testing is needed. There was also a bug with the...

The last one I made isn't the fastest, but a compressed version that uses the previous fast one. Here's the fast one (it took me a few days to create the macro on one line like you did; I'm going crazy.) :: make sure we are in the spotlight: :: run as administrator for realtime priority!!! :: /affin...

even shorter. setlocal set "args=%1 %2" for /f "tokens=1-3" %%1 in ("!args! FEDCBA9876543210") do ( if defined %%~1 ( if "" neq "!%%~1:~255!" ( if "" neq "!%%~1:~4095!"

I was referring to the slowing down of the "set": Why does SET performance degrade as environment size grows? This is a version that reduces the macro size while still maintaining almost all of its speed. It's a good fit for me. setlocal set "args=%1 %2" for /f "tokens=1,2" %%1 in ("!args!") do ( if...

I tried to optimize the upper part even more, this is the code and the times setlocal set "args=str len" for /f "tokens=1,2" %%1 in ("!args!") do ( if defined %%~1 ( if "" neq "!%%~1:~255!" ( if "" neq "!%%~1:~4095!" ( set "$=!%%~1:~4095!" ) else set "$=!%%~1!" set "$scale=!$:~255,1!!$:~511,1!!$:~76...

I made another version that's even faster, but I discarded it because the macro was too long and the env for Win 10 is a problem.

I haven't tried it on Windows 11, but they told me the set problem related to the env size is no longer there.

Do you know if this is the case?

I took the last one you made and optimized it a bit. I removed a "Set" from everything and removed another set for some lengths. Also in the upper part from 4096 to 8192. I compared it, and it's faster than the last one. Of course, I compared the code without the macros. I think you'll have to figur...

It's been a year since the version I had on my PC. Yours seems faster. I haven't had time to study it. I added it to the old tests and I think the added checks and setlocal slow it down a bit. Now I'm studying it to see if there's anything I can improve on in terms of speed. @echo off setlocal Enabl...

"_SIN=a-a*a/1920*a/312500+a*a/1920*a/15625*a/15625*a/2560000-a*a/1875*a/15360*a/15625*a/15625*a/16000*a/44800000" this seemed to have an algorithm protection ex) 1+3 =4 or (1/2 + 3/40*20)*200/100=4 there is no protection, if you calculate the third term for x=7000, with your formula it gives 13...

@miskox I'm trying that formula 10000*y/10/2 and mathematically since there is a multiplication by 10000 (which has 2 and 5 among the prime factors) the division by these should give an exact integer result without remainder or fractional part. That is, for any Y in that formula there is no remainde...

... In addition worked around the bug: "if 2147483647 LSS -1 echo true" echoes "true" on windows xp home 32 bit (?!) but it's not a bug only for "-1" it does it for all the pairs that have the same representation and with the bit sign different. At least it seems to me. On win10 if 2123153877 lss -...

basically the question is this. Is it possible to bypass the endlocal barrier/tunnel inside a call of variables that have LF or in any case the code to create multiline macros? I enter the procedure with the value of the delayed variables or active or inactive, then I activate it if necessary, I do ...

I explained myself badly. I expanded the code hoping that you can understand where I'm having difficulty I have a code that reads a file and prepares the macro in this format: set macro=<code>[LF]<code>[LF]<etc> @echo off setlocal enabledelayedexpansion rem From Honguito98 idea call :AutomacroLite "...
