loop标签的执行顺序

新建下面的bat文件

@echo off

SET START_MACHINE=0


for %%i in (1 2) do call :LOOP

echo goto eof
goto EOF

:LOOP
@echo here is loop pp


:EOF
echo here is eof

if %START_MACHINE%==0 (
echo 111 first time
SET START_MACHINE=1
) else (
echo 222 second time
@echo wait 5s ss
ping /n 5 127.1>nul
)

pause

执行顺序为 call :LOOP的地方调用两次loop标签，两次都从loop标签执行到结束，然后回到for语句下面那句，goto eof，继续执行标签EOF
也就是执行顺序为：LOOP----EOF-----LOOP----EOF-----EOF

@echo off

SET START_MACHINE=1

for %%i in (1 2) do call :LOOP

echo goto eof
goto EOF

:LOOP
@echo loop


:EOF
@echo eof
if %START_MACHINE%==1 (
SET START_MACHINE=2
@echo 111
) else if %START_MACHINE%==2 (
SET START_MACHINE=3
@echo 222
) else if %START_MACHINE%==3 (
ping /n 5 127.1>nul
@echo 333
pause
)
