This one beats me completely, but I think this trick by Benny Pedersen is absolutely brilliant, amazing . . .

Hi,

This batch file returns the Errorlevel parameter as a two digit HEX
number but I can't figure out of any purpose so maybe it's useless?

Benny Pedersen,


@ECHO OFF
%COMSPEC% /C rem THIS LINE SET THE ERRORLEVEL PARAMETER = 0d (00h).

FOR %%! IN (0  A  B  C  D  E  F  G  H  I  J  K  L  M  N  O) DO IF ERRORLEVEL %%!0000 SET A=%%!
FOR %%v in (00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15) DO IF ERRORLEVEL %A%00%%v SET B=%%v
ECHO %A%|CHOICE/c'0ABCDEFGHI'''''''JKLMNO>NUL
FOR %%v in (1 2 3 4 5 6 7 8 9 A B C D E F) DO IF ERRORLEVEL }%%v SET A=%%v
FOR %%v in (0 1 2 3 4 5 6 7 8 9) DO IF %B%==0%%v SET C=%%v
IF NOT (%C%) == () GOTO Result
FOR %%v in (0 1 2 3 4 5) DO IF %B%==1%%v SET C=%%v
ECHO %C%|CHOICE/c012345>NUL
FOR %%v in (A B C D E F) do IF errorlevel H%%v SET C=%%v
:Result

ECHO. The Errorlevel parameter was %A%%C% (hex)

FOR %%v in (A B C) do SET %%v=
CHOICE /c THIS LINE SET THE ERRORLEVEL PARAMETER = 255d (FFh) > NUL

@ECHO OFF
%COMSPEC%/c rem THIS LINE SET THE ERRORLEVEL PARAMETER = 0d (00h).
CHOICE/c THIS LINE SET THE ERRORLEVEL PARAMETER = 255d (FFh) > NUL

SET B=F
FOR %%! IN (0 A B C D E F G H I J K L M N O) DO IF ERRORLEVEL %%!0000 SET A=%%!
FOR %%! in (E D C B A @) DO IF NOT ERRORLEVEL %A%00I%%! SET B=%%!
IF @==%B% FOR %%! in (0 1 2 3 4 5 6 7 8 9) DO IF ERRORLEVEL %A%000%%! SET B=%%!
ECHO %A%'|CHOICE/c'0ABCDEFGHI'''''''JKLMNO>NUL
FOR %%! in (1 2 3 4 5 6 7 8 9 A B C D E F) DO IF ERRORLEVEL }%%! SET A=%%!
ECHO. Errorlevel %A%%B%h
FOR %%! in (A B) do SET %%!=

How about a hexadecimal number for your current drive?

CD | CHOICE /C:ABCDEFGHIJKLMNOPQRSTUVWXYZ >NUL
SET B=F
FOR %%! IN (0 A B C D E F G H I J K L M N O) DO IF ERRORLEVEL %%!0000 SET A=%%!
FOR %%! in (E D C B A @) DO IF NOT ERRORLEVEL %A%00I%%! SET B=%%!
IF @==%B% FOR %%! in (0 1 2 3 4 5 6 7 8 9) DO IF ERRORLEVEL %A%000%%! SET B=%%!
ECHO %A%'| CHOICE /C:'0ABCDEFGHI'''''''JKLMNO >NUL
FOR %%! in (1 2 3 4 5 6 7 8 9 A B C D E F) DO IF ERRORLEVEL }%%! SET A=%%!
ECHO. Errorlevel %A%%B%h
FOR %%! in (A B) do SET %%!=
