set str=%!str!:~-3% 换成
set str=!str:~-3! 看看

大概是屏幕窗口限制！因为从1到100就是完整的

最短的:  (如果没有 edit.exe, 就改 write, 再不然就改 notepad)

cmd /v:on /q /c "del ~&(for /l %%a in (9001,1,9999) do set n=%%a&echo !n:*9=!>>~)&edit ~"
复制代码

长一点的:

cmd /v:on /q /k "mode con lines=1001&(for /l %%a in (9001,1,9999) do set n=%%a&echo !n:*9=!)"
复制代码

再长点的:

echo off&mode con lines=1000&setlocal enabledelayedexpansion&(for /l %%a in (1001,1,1999) do set n=%%a&&echo !n:*1=!)&pause
复制代码

楼主你的方法太帅了，又学到一招，呵呵

@echo off

答：

@echo off
:1
set /a js+=1
set mun=%js%
if %js% lss 100 set mun=0%js%
if %js% lss 10 set mun=00%js%
echo %mun%
if "%js%"=="999" goto 2
goto 1
:2
pause

@echo off
for /l %%i in (1,1,999) do (
set var=00%%i
call echo %%var:~1,-3%%>>1.txt
)
1.txt

这个最经典，最简洁

虽然还有一个代码：也蛮简洁的：但是扩展性不好。

 
for /l %%i in(1,1,9) do echo 00%%i
for /l %%i in(10,1,99) do echo 0%%i
for /l %%i in(100,1,999) do echo %%i
