[Question] Echoing Veriables in Veriable..

[Ranguna173]

Hello! I haven't been here for a while!!
I'm gonna start learning XNA.. But Batch will always be here in my heart

Anyway, I have been trying to echo a variable inside another variable like this:

Code: Select all

C:>set SRC=1

C:\>set SR%SRC%=12

C:\>echo %SR1%
12

C:\>echo %SR%SRC%%
%SR1%

C:\>wtf?!

See there, when I echo %SR1% the output is 12 but then if I echo %SR%SRC%% the output is %SR1%

Help Please.
Thanks

Anyone??

Code: Select all

@echo off
set SRC=1
set SR%SRC%=12
echo %SR1%
call echo %%SR%SRC%%%
pause

It doesn't function from a cmd prompt.

echo %SR1%
call echo %%SR%SRC%%%
pause

Thank You Very Much!!!
Oh, and it is %SR%SRC%% not %%SR%SRC%%, I think cmd processes empty spaces in variables
See It is like
1st Processes the variable-
%SR%SRC%%
2nd it reads the deepest variable-
%SR1%
3rd It reads the next variable (SR%SRC%=12 which is the same thing as SR1=12)-
12

Didn't thought about manualy calling the variable..

Thanks

Wait it doesn't work again.. Tha' he**?

try copy/paste again.

[!k]

Code: Select all

@echo off
set SRC=1
set SR%SRC%=12
echo %SR1%
call echo %%SR%SRC%%%
pause

or

Code: Select all

@echo off
setlocal enabledelayedexpansion
set SRC=1
set SR%SRC%=12
echo %SR1%
echo !SR%SRC%!
pause

[Ranguna173]

Code: Select all

@echo off
setlocal enabledelayedexpansion
set SRC=1
set SR%SRC%=12
echo %SR1%
echo !SR%SRC%!
pause

Nop The out put is !SR1!
It should be 12.

try copy/paste again.

Hehe.. Looks like it doesn't work..

I have to do this:

Code: Select all

C:>set SRC=1

C:\>set SR%SRC%=12

C:\>echo %SR1%
12

C:\>echo %SR%SRC%%
%SR1%

C:\>call echo %SR%SRC%%
%SR1%

C:\>set SR1=12

C:\>echo C:\>echo %SR%SRC%%
12

C:\>echo C:\>call echo %SR%SRC%%
12

C:\>weird..

Thanks for your time.

It looks like you have the random behaviour generator bug in your cmd window. Reboot your PC.

Both these work.

@echo off
set SRC=1
set SR%SRC%=12
echo %SR1%
call echo %%SR%SRC%%%
pause

@echo off
setlocal enabledelayedexpansion
set SRC=1
set SR%SRC%=12
echo %SR1%
echo !SR%SRC%!
pause

Hmm.. Maybe My commands are to complex for CMD and it just starts messing with me..
I'll try that.

Thanks!

Nop The output for your code is %%SR1%% and the output for !k's is !SR1! ...

Don't worry about it, I'll just code somthing else...

Are you running the batch files or working at the command line?
