用了N多的FOR：

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%i in (a.txt) do (
    set str=%%i
    if "!str:~0,1!"=="A" (
        set var=!str:~-3!
        if !var! gtr 0 if !var! lss 999 set /a n+=1
)
call,set ".!n!=%%.!n!%%"%%i" "
)
for /f "tokens=2 delims==" %%i in ('set .') do (
    for /f "tokens=1" %%a in ("%%i") do (
        set hh=%%a&set num=!hh:~2,3!&set _!num!=%%i
))
for /f "tokens=2 delims==" %%i in ('set _') do (
    for %%b in (%%i) do echo %%~b
    echo\
)
pause
