Dos script error: identical result after some iterations

[auberns]

Hello all,

I'm new in this forum. So let me know if I post in the wrong place. I have a script that gives wrong results after a few iterations. Could anybody tell me why the result remain the same after a few iterations (something like 75 iterations). Here is my script:

@echo off
setlocal enabledelayedexpansion

for /f %%G in ('dir /b /o:n *.mp3') do (
call :printVal 30 %%~nG
set CP=!var!
echo !CP!>> run1.txt
)
goto:eof

:printVal
for /L %%a in (1,1,%1) do set zero= !zero!
set var=!zero!%2
set var=!var:~-%1!
goto :eof

Thank you for your responses,
Nicolas

This can happen, if your filename contains more than 30 characters because you cut it.

I modified this to support long filenames and it works ok on 160 files.

We need to know what your input name format is - but the line that resets zero might be needed too or else you could hit the length limit for that variable.

Code: Select all

@echo off
setlocal enabledelayedexpansion
del run1.txt 2>nul
for /f "delims=" %%G in ('dir /b /o:n *.mp3') do (
call :printVal 30 "%%~nG"
set CP=!var!
echo !CP!>> run1.txt
)
goto:eof

:printVal
set "zero="
for /L %%a in (1,1,%1) do set zero= !zero!
set "var=!zero!%~2"
set "var=!var:~-%1!"
goto :eof
