【已解决】批处理type中，循环语句如何表示？

思想之翼

D:\DATA\文件夹中有500个文本，分别命名为1.txt 2.txt...500.txt

欲1.txt 与 2.txt合并，3.txt 与 4.txt合并......499.txt 与 500.txt合并

type D:\DATA\1.txt > D:\DATA2\1.txt
type D:\DATA\2.txt >> D:\DATA2\1.txt

type D:\DATA\3.txt > D:\DATA2\2.txt
type D:\DATA\4.txt >> D:\DATA2\2.txt
......
type D:\DATA\499.txt > D:\DATA2\250.txt
type D:\DATA\500.txt >> D:\DATA2\250.txt

@echo off
setlocal enabledelayedexpansion
for /l %%f in (1,1,250) do (
    set q=%%f
    type D:\DATA\!q!*2-1.txt > D:\DATA2\!q!.txt
    type D:\DATA\!q!*2.txt >> D:\DATA2\!q!.txt
)
endlocal
exit

上述代码标红处，如何正确表示？

1. @echo off
   
2. setlocal enabledelayedexpansion
   
3. md "D:\DATA2" 2>nul
   
4. cd /d "D:\DATA"
   
5. for /l %%i in (1,2,499) do (
   
6.     set /a m+=1
   
7.     set /a n=%%i+1
   
8.     type "%%i.txt" "!n!.txt" 2>nul>"D:\DATA2\!m!.txt"
   
9. )
   
10. pause
