     Examples from a News Group [MSDOS.BATCH] Jan 23, 01

     The following batch program is solid as a rock i.e.
     it should be okay to use it as a templete for other
     solutions. It don't hanging in endless loops and no
     temporary files or other files are written and when
     the batch is over, then all variables, which I used
     is completely cleaned up.

     The batch file contains information about:

     1.: How to convert an input from lower to uppercase
         or upper to lowercase.

     2.: How to count a number of elements in a variable
         %v% using choice:

         echo.. | choice /c'%v%..COUNT: Set D=Number of elements >nul
         for %%v in (1 2 3 4 5 6 7 8) do if errorlevel }%%v set D=%%v
         echo Number of elements are: (%D%)

         etc...

     Delimit8.bat

     Normal usage:
         delimit8.bat number
         Returns all digits of the number.

     Examples:
         delimit8 01437
         Returns D= 0 1 4 3 7

     Wrong usage i.e. other characters than numbers:
         delimit8 bc45px3
         Returns D= 4 5 3

         delimit8 125,34
         Returns D= 1 2 5

     Test.bat: (tested on DOS6.22 (USA version) and Win98 (DK version))
         @echo off
         call delimit8 33
         delimit8

     Tips:
         Reverse the order of %D% and %%D (line number 3), "D=%%D %D%"
         instead of "D=%D% %%D" and the output will be reversed.

     Notes:
         If an input consist of more than 8 characters, then it
         truncates the input of the first 8 characters.

    If one wanted to only display the ramdrive letter, one could
    eliminate the PROMPT and both CTTY commands.

    FOR %%d in (Z...C) do IF errorlevel H%%d %COMSPEC%/C ECHO Ramdrive=%%d

    Still no SET command in sight, no extra blank line from CTTY, no 'file
    not found' message to mask, and the prompt is not altered. Also, one
    should not assume EBD exists on unknown systems, or that the user copied
    FINDRAMD.EXE into %windir%\command directory (mine has neither).

 Benny wrote:
    Yes you right about that! My reson for the code was not a program but
    a syntax solution. Now, you found that it's okay to reverse the order
    Z...A and use a "%COMSPEC% /C". This is much better... (Thanks Todd).

    ECHO is not OFF in a second COMMAND.COM session.

    A general conclusion:
    If it's about avoiding the SET command and still be able to executing
    particular commands, then it would normally be necessary to neste two
    IF statements. Example: IF errorlevel "A" IF NOT errorlevel "A +1"...
    My previours research about the bennyLevels (I never told about this)
    shows that it's NOT possible to create such two nested IF statements.
    The solution for this problem seems to be, a reverse order of all the
    elements in the FOR loop and this in combination with "%COMSPEC% /C".

    If it's just one command that we wanted, then the

    FOR %%d in (Z ... A) do IF errorlevel H%%d %comspec% /c SOMETHING...
    is useful.

    What I was trying yesterday was to figure out how to do an "ECHO OFF"
    in a second/another COMMAND.COM session.

    After a good sleep, I just found what I was searching. It goes here:

    ctty:nul
    FOR %%d in (Z ... A) do IF errorlevel H%%d %comspec% /c for %%v in (
echo:off ctty:con echo.%%d %%d: cd\ md:test pause cls) do %%v

    The above don't have to be used in combination with errorlevels. The
    point is that the "ECHO OFF" works in the second COMMAND.COM session
    and no SET commands are used ;-)

Calculating and converting or use this method...

X = dec2hex(160(n-1)) and the range of n is [1;25] (dec).
Example: if n = 2, then X = A0

Instead of writing a batch, which calculates and converts
the above result (X), then we can write 25 lines as:

if %n%==1  set X=00
if %n%==2  set X=A0 ... and so...
if %n%==25 set X=F00  but we can also use the following method:

          @echo off>~.bat
          for %%v in (0 A 14 1E 28 32 3C 46 50 5A 64 6E 78 82 8C 96 A0 AA B4
 BE C8 D2 DC E6 F0) do echo.   @set %%1=%%v0>>~.bat

          set n=2
          find ""/v/n<~.bat |find "[%n%]">~.bat

Compare the size of the above batch code with other methods.
Ok, here's the script:

          rem>~.scr
          for %%v in (f100L7''9 w q) do echo %%v>>~.scr
          debug ~.bat<~.scr>nul

Since n = 2, then
          CALL ~ X
would put A0 (hex), ((n-1)(2)(80) (dec) = 160n -160 (dec)) into
a variable named X.

Notes: The above method, (using FIND ""/v/n), can be used on big files, (any
number of lines [1;65535] and not just as the above example were I used, the
range [1;25] so, I have substituted "echo.@" with "echo.   @" and L4 with L7
in the above FOR loop and in the small script).
