I have come to an unexpected result when testing with my batch file. This result can also be generated at the prompt. >echo. | set /p ".=a15(51|62)" a15(51|62) >echo. | set /p ".=a15(51|62)" | clip > The first command displays the result correctly. The second command copies the r...

Please see more informations: CALL /? Here a small batch file: @echo off setlocal :: echo %1 %~a1 set test=%~a1 set test=%test:~0,1% if %test%==d (echo %1 is a directory) else echo %1 is not a directory Tested in Win7. Here some examples: D:\CMDVerz>exattr InRegEx5.bat InRegEx5.bat is not a director...

Here a batch file to calculate the Square root. The steps correspond to the calculation with decimal numbers, but here the calculations on binary numbers are optimized. BATCH value BATCH value IEEE value "Value" is an integer from 0 through 2147483647. The result is calculated to four deci...

@dbenham Thank you. The code has previously worked well up to this point. But after the code change I have probably not tested again this part. Change the condition for the perfect squares greater 100. Also change condition for the not perfect squares (now checked with variable zahl2). The result wi...

I have changed the code. Now the pure square numbers less than 100 are also correct. The result has now less one decimal place, but this is rounded. @echo off SetLocal EnableDelayedExpansion echo Square Root set para=%1 if %1# equ # (echo ERROR no number or negativ number) & echo. & goto :eo...

Calculating Square Root Here the mathematic rules: (a + b)^2 = a^2 + 2ab + b^2 = a^2 + (2a + b) * b (a + b + c)^2 = a^2 + 2ab + b^2 + 2ac + 2bc + c^2 = a^2 + (2a + b) * b + (2a + 2b + c) * c Here my code @echo off echo Square Root set para=%1 if %1# equ # (echo ERROR no number or negativ number) &am...

This code creates a batch file that shows the differences with the German letters between CP1252 and CP850. Hint: Microsoft Windows OS versions newer than XP contain certutil.exe. Older OS versions may be able to install certutil.exe as part of another package, e.g. the Windows 2003 Server Service P...

The following code need a parameter (name of city) to check this in in file. Don't use quotes in the parameter. BATCH Saarbrücken BATCH Frankfurt (Main) @echo off setlocal EnableExtensions REM in Windows found the German characters in CP1252 and CP1250 at the same position REM check: input Alt+0165 ...

This files are not the complete MS-DOS 6.22 system.

If you have install the system at the hard drive before, then use this files (boot CD) when your old MS-DOS system will not boot.

This is not nothing for the newest computer with hard drive capacity with more than 2 GB (2.000 MB).

Your code need to change the row to: ... findstr /v "^Total" < "%name%" >"X:\FOLDER\%dd%%mm%%yyyy:~2%Q.txt" ... The letter X: is the USB drive (USB pen) and FOLDER is the path at this drive. The letter of the USB drive is not anytime the same letter. Possible is this pr...

In this forum was a thread and there also a link to a calculator:

See there: STR_MATH.BAT

In Win XP parameter /-S or /-Q are not possible for internal commands RD or RMDIR.

I think that this parameter are work with a predefineted variable.

See also the commands DIR or COPY with the variable DIRCMD or COPYCMD.

Here a example code: @echo off set StringDestination=### for %%a in ("C:\source\*.txt") do set StringOrigin=%%~na for /l %%d in (1, 1, 5) do echo File: "C:\OutputFolder\%StringDestination%%%d%StringOrigin%.dat" The batch find one txt-file in the folder "C:\source\". If ...

Here I have change my code. @ECHO off :again ECHO. ECHO 1) Calculator ECHO 2) Timer ECHO 3) Exit SET /P OPT=Which option would you like? IF %OPT%==1 GOTO :Calculator IF %OPT%==2 GOTO :Timer IF %OPT%==3 GOTO :Exit GOTO :again :Calculator ECHO "Code for Calculator" GOTO :again :Timer ECHO &q...

The following code make a menu. If you will input not a number 1, 2 or 3 then will see the menu again. Every subroutine need an endpoint. This end point may be: - last command in the batch - go to another point in the batch GOTO :zzz - go to the end of the batch :EOF - exit the batch with or without...
