Batch: During my code loop it stops setting a variable. All Help Welcome

问题

goto time

:time
set tm=%time%
set hh=%tm:~0,2%
set mm=%tm:~3,2%
set ss=%tm:~6,2%
set ms=%tm:~7,2%
goto date

:date
set dt=%date%
set wd=%dt:~0,3%
set mh=%dt:~4,2%
set dy=%dt:~6,2%
set yr=%dt:~8,4%
goto scheduletimes

:scheduletimes
goto hour1
:hour1
for /f "tokens=1*delims=0" %%a in ("$0%hh%") do set /a "HH"="%%b"
if %HH% equ 6 goto minutes1
pause
goto time
:minutes1
for /f "tokens=1*delims=0" %%a in ("$0%mm%") do set /a "MM"="%%b"
if "%MM%"=="00" goto seconds1
pause
goto time
:seconds1
for /f "tokens=1*delims=0" %%a in ("$0%ss%") do set /a "SS"="%%b"
if %SS% lss 10 goto day1
pause
goto time

:day1
echo success
echo %hh%
echo %mm%
echo %ss%
pause 
goto time

As you guys can see this is a time check loop. Seeing if the time is 6:10:>10. Basically what my problem is though is that it runs fine until it executes the command when it hits that time. As soon as it becomes <10 seconds in this section:

:minutes1
for /f "tokens=1*delims=0" %%a in ("$0%mm%") do set /a "MM"="%%b"
if %MM% equ 0 goto seconds1

it stops setting MM to %mm% and it gives me a Missing Operand error.

Any help would be appreciated to get it to continue working after the first run.

(Yes I do know there are pauses and no @echo off, This is for debugging purposes. It does it with the @echo off and without the pauses too)

Press any key to continue . . .

回答1:

Please note, batch does not differentiate between %mm%and %MM%. Try this:

:minutes1
set /a min=0
for /f "tokens=1*delims=0" %%a in ("$0%mm%") do set /a min=%%b 2>nul
echo %min%
if %min% equ 0 goto seconds1

回答2:

Perhaps you have a fundamental problem with delims=0. If the value is 00 you will get nothing. So you need to quote some variables

if "%HH%"=="6" goto minutes1

and

if "%MM%"=="" set MM=0 & goto seconds1

and add the first line below

if "%SS%"=="" set SS=0
if %SS% lss 10 goto day1
