I know I can write an echo > C:/Folder/name.txt
But I have a generator to make 2 number for Cord and can't figure out a quick way to make a one line echo > with all the points
for shortness I'll simplify my code because the current code is not the issue
Echo off
Setlocal EnableDelayedExpansion
set R=1
set Number=1
:Loop
if %R% EQU 1 (set /p Max=How many Max Points? ) Else(
echo.)
set /p PX%number%=What is PointX%number%?
set /p PY%number%=What is PointY%number%?
if %Number% GEQ %Max% (goto :fin) Else(
set /a Number=%Number%+1 & set R=2 & Goto :loop)
This Is what Im trying to Optimize
:fin
echo (%PX1%,%PY1%),(%PX2%,%PY2%),(%PX3%,%PY3%) ... Ect >C:Folder/File.txt
Is there any way to make all the generated numbers on 1 line

Correct Code:
Echo off
Setlocal EnableDelayedExpansion
set R=1
set Number=1
set Line=Test
:Loop
if %R% EQU 1 (set /p Max=How many Max Points? ) Else (
echo.)
set /p PX%number%=What is PointX%number%?
set /p PY%number%=What is PointY%number%?
set line=%line%(!PX%number%!,!PY%number%!),
if %Number% GEQ %Max% (goto :fin) Else (
set /a Number=%Number%+1 & set R=2 & Goto :loop)
:fin
echo %Line:~0,-1% >C:Folder/File.txt

The logic is so much simpler if you get the max point count before the loop. And the FOR /L loop can auto increment your counter and eliminate the need for GOTO.
#echo off
setlocal enableDelayedExpansion
set /p "cnt=How many points? "
set "ln="
for /l %%N in (1 1 %cnt%) do (
echo(
set /p "PX%%N=What is PointX%%N? "
set /p "PY%%N=What is PointY%%N? "
set "ln=!ln!(!PX%%N!,!PY%%N!),"
)
echo(
echo !ln:~0,-1!

I have a project for square root calculation to get the larger side of in a right triangle using Pythagorean theorem.
Here's what I've tried :
#echo off
set /p a=Pleas Enter Value(1) =
echo.
set /p b=Pleas Enter Value(2) =
set /a c=%a%*%a%
set /a d=%b%*%b%
set /a F=%d%+%c%
echo.
:calculation Value(3)
rem root Number
√%F%
echo.
pause>nul
Batch
This is the native batch method(not accurate):
set divider=0
:loop
set /a divider=divider+1
set /a sqrt=F / divider
if %divider% equ %sqrt% goto break
if %divider% gtr %sqrt% goto break
goto loop
:break
echo %sqrt%
It will floor the number if the square root is floating point number.
Again, will not support floating point arithmetic, but this code works:
#echo off
Title SquareRoot
:StartSquareRoot
cls
echo Number:
set /p number=
call :SquareRoot %number%
echo Square: %number%
echo Root: %answer%
pause
goto StartSquareRoot
:SquareRoot
set root=1
set /a sqr=%root%*%root%
:Loop
if %sqr% LSS %number% (
set /a root=root+1
set /a sqr=root*root
goto Loop
)
(EndLocal && set answer=%root% && exit /B)
I couldn't get %difference_two% to work It can find %difference_one% as 2 but when I make it divide 2 by 2 it doesn't display as anything.
Use the numbers 2,5,10,17,26
To get what I need.
#echo off

In batch, commands in a code block (between ( )) are interpreted as on the same line, so you need to use setlocal EnableDelayedExpansion and use ! instead of % inside them.
I am trying to create a matrix this one works below) but is slow as it has to loop every number. So i was wondering if you can have multiple %random% %% 2 without just a "(random number) %2" being printed.
#echo off
color 0a
:a
set /a mat=%random% %% 2
echo |set /p=%mat%
goto a
I found this to be much faster:
#echo off
if not "%1" == "max" start /MAX cmd /c %0 max & exit/b
color 0a
setlocal EnableDelayedExpansion
:a
set "addition="
for /L %%i in (1,1,256) do (
set /a mat=!random! %% 2
set addition=!addition!!mat!
)
echo |set /p=%addition%
goto a
EDIT: I now see that the answer #Stephan links to in the comments is very similar, so credit goes to him too.
EDIT #2:
You might like this one too, has all kind of characters so it looks a bit more "matrixy"
#echo off
if not "%1" == "max" start /MAX cmd /c %0 max & exit/b
color a
setlocal EnableDelayedExpansion
set "CHARS=abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789######$$$%%%%%%*** "
echo %CHARS%>x&for %%? in (x) do set /a strlength=%%~z? - 2&del x
:a
call :randomString addition 100 "%chars%" %strlength%
echo |set /p=%addition%
goto a
:randomString
set "length=%2"
set "CHARS=%~3"
if ["%CHARS%"]==[""] set "CHARS=abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789######$$$%%%%%%***"
set "strlength=%4"
if [%strlength%]==[] echo %CHARS%>x&for %%? in (x) do set /a strlength=%%~z? - 2&del x
set "line="
for /L %%a in (1 1 %length%) do (
set /a "randnr=!random!%%!strlength!"
for /l %%n in (!randnr! 1 !randnr!) do set "line=!line!!CHARS:~%%n,1!"
)
set %1=%line%
exit /b
For extra effect add 6 spaces to the CHARS variable. Note that I also added a line to start it in full-screen mode.
The method below is the fastest possible way to solve this problem:
#echo off
setlocal EnableDelayedExpansion
rem Prepare the output for one line
set "bin=0101010101"
set "line="
for /L %%i in (1,1,79) do (
set "line=!line!%%bin:~^!random:~-1^!,1%%"
)
for /L %%i in () do call echo %line%
I have a file with this output:
ANS8000I Server command: 'ru FailedReport'
Unnamed[1]
------------
9
Unnamed[1]
------------
110
Unnamed[1]
------------
101
I need to take those numbers, and assign it to three different variables. I made this script, but I can't make it to work... I always got "0" as result.
#echo off
setlocal enableextensions enabledelayedexpansion
set /A counter=0
SET /A failed=0
SET /A completed=0
SET /A total=0
for /F "tokens=1 skip=4" %%a in (C:\Users\Desktop\Aux.txt) do (
if "%counter%" EQU 5 (set /A failed=%%a)
if "%counter%" EQU 9 (set /A completed=%%a)
if "%counter%" EQU 13 (set /A total=%%a)
set /A counter+=1
)
echo "Failed: " %failed% >> C:\Users\Desktop\Result.txt
echo "Completed: " %completed% >> C:\Users\Desktop\Result.txt
echo "Total: " %total% >> C:\Users\Desktop\Result.txt
Could anyone help me with this? I tried a lot of combinations (variables with !, %, %%), but I still got the same result.
Thanks!!!
#ECHO OFF
setlocal enableextensions enabledelayedexpansion
set /A counter=0
SET /A failed=0
SET /A completed=0
SET /A total=0
for /F "tokens=1" %%a in (q24152955.txt) do (
ECHO !counter! %%a
if !counter! EQU 3 (set /A failed=%%a)
if !counter! EQU 9 (set /A completed=%%a)

I used a file named q24152955.txt containing your data for my testing.
In delayedexpansion mode, %var% refers to the original value of var - before the loop began execution and !var! is the dynamic value - as it changes.
"something" is never going to be equal to something because the quotes are significant. Quoted values are often used in this context in case the value itself is empty or contains special characters (especially spaces) - "" is a non-empty string.
for /f ignores empty lines. I've included a superfluous echo command to show which lines the for processes. Note that the value of counter is thus the sequential number of non-empty lines in the file, not the actual line number. Note also that a line containing just one (or more) spaces is not an empty line!
#ECHO off&cls
setlocal enabledelayedexpansion
set "$count=1"
for /f "delims=" %%a in (C:\Users\Desktop\Aux.txt) do (
if !$count!==4 set failed=%%a
if !$count!==7 set completed=%%a
if !$count!==10 set total=%%a
set /a $count+=1
)
(echo Failed : %failed: =%
echo Completed : %completed: =%
echo Total : %total: =%)> C:\Users\Desktop\Result.txt
I have been having troubles with batch-codes that I would expect to work, but don't...
Below is what I have written...
#echo off
cls
:loop
set /p "input=Input a number: "
set /a "number=%input%" 2>nul
REM check if input valid
if "%input%" NEQ "%number%" (
cls
Echo Please Enter a valid number! &Echo.&Echo.
goto :loop
)
Set /a Even=number%%2
if %Even% EQU 0 (
Echo Substituting Even Number in: x / 2
Echo set /p"=(%number%) / 2 = "
set /a answer=number/2
) Else (
Echo Substituting Odd Number in: 3x - 1
<nul set /p"=3(%number%)-1 = "
set /a answer=number*3
set /a answer=answer-1
)
Echo %answer%
Echo.
Echo.
goto :loop
Echo Unexpected Error . . .
pause
Exit
Whenever I input a number into the console, it does the math, like I want it to, but prints the number -1, and every time i input another number, the number goes to -2, -3, -4, so on.
Put a setlocal enableextensions at the beginning after the #echo off, e.g.
#echo off
setlocal enableextensions
cls
Also, I think you would also need to use delayed variable expansion (usually denoted by !var!), which would change your script above to something like this:
#echo off
setlocal enableextensions enabledelayedexpansion
cls
:loop
set /p "input=Input a number: "
set /a number=!input! 2>nul
REM check if input valid
if "!input!" NEQ "!number!" (
cls
Echo Please Enter a valid number!
Echo.
Echo.
goto :loop
)
REM Make sure that it is an integer put in (just in case)
set /a int=!number! %% 1
if "!input!" NEQ "!int!" (
cls
Echo Please Enter a valid number!
Echo.
Echo.
goto :loop
)
Set /a Even=!number! %% 2
if !Even! EQU 0 (
Echo Substituting Even Number in: x / 2
set /a answer=!number! / 2
) Else (
Echo Substituting Odd Number in: 3x - 1
set /a answer=!number! * 3 - 1
)
Echo !answer!
Echo.
Echo.
goto :loop
I also would like to point out that I also fixed a few other bugs (set /p isn't of any use in this script at all, especially in where it is used, and also you need the modulus to find even/odd).
