COLOR TIME Color Time Screen Saver - China DOS Union Forum

The processing has reached such a level, really an outstanding person! Take it down and savor it slowly

The effect of removing call is the same.

The role of call is sometimes very big.

@echo off
set a=1
echo %a%
call :aa a
echo %a%
goto :EOF

:aa
call set %1=2
goto :EOF

The first sentence call is the job content

The second sentence call is an unnecessary addition

set %1=2

And

call set %1=2

The results are not different

In the following example call is useful


@echo off
set a=1 2 3
echo %a%
call :aa a
echo %a%
goto :EOF

:aa
call set %1=%%%1%% 4 5 6
goto :EOF

Please clarify your request. Are you asking for a translation of this Chinese text into English as per the given requirements? If so, here is the translation:

请问 qzwqzw :

1.---------------------------
call set %1=%%%1%% 4 5 6

Before the code is tested and run, how to determine how many % symbols to use.

2.---------------------------
call set %1=%%%1%% 4 5 6 is equivalent to set %1=%a% 4 5 6

Is there a necessity for call set.

Wow~~~~~Pretty impressive, though I didn't understand it.... Sweat~~

Add another pair of %%

call set %1=%%%1%% 4 5 6
↓
call set a=%%a%% 4 5 6
　　↓
set a=%a% 4 5 6

@echo off
set a=1 2 3
echo %a%
call :aa a
echo %a%
goto :EOF

:aa
call set %1=%%%1%% 4 5 6
goto :EOF

The understanding is good. To a certain extent, the role of call is to substitute variable delay

@echo off
setlocal enabledelayedexpansion
set a=1 2 3
echo %a%
call :aa a
echo %a%
pause
goto :EOF

:aa
set %1=!%1! 4 5 6
goto :EOF

---qjbm-----------

Q1: The general principle is that you use as many % as the number of times you need to parse.

For example, call set %1=%%%1%% 4 5 6

Before the call is executed, the command line has been processed into a form like this:

call set a=%a% 4 5 6

After the call is executed and before the set is executed, the command line becomes like this:

set a=1 2 3 4 5 6

Q2: When the variable name used in the aa segment is uncertain or dynamically changing, call set is useful.

---PPdos----------------------------------

Understood well.

But it is more appropriate to understand it the other way around -

The role of variable delay l is to a certain extent to replace call.

Because the usage of call appeared much earlier.

Before there was cmd.

In DOS, call was used to implement the pass-by-reference feature similar to C language.

Great, collect it and study it slowly~~~~~~

The creativity is quite good. Just there are too many unnecessary sentences. Simplify it.

Haven't been here to post for a long time.

Saw a lot of good things today.

Studying intensively right now.
