@echo off
set /a m=0
call :111 A B C
pause&goto :eof
:111
set /a m+=1
set /a n=m+1
set /a l=m+2
call echo %%%m% %%%n% %%%l%
goto :eof

其中的call echo %%%m% %%%n% %%%l%用setlocal enabledelayedexpansion
endlocal 启用延迟变量 如何表达？

@echo off

setlocal enabledelayedexpansion

set /a m=0

call :111 A B C D E F G

pause&goto :eof

:111

ping 127.1 -n 2 >nul 2>nul

set /a m=!m!+1

set /a n=!m!+1

set /a l=!n!+1

call echo %%!m! %%!n! %%!l!

if /i !m! gtr 8 (goto :eof) else (goto 111)

goto :eof

运行看一下，就明白了吧？
