Problem with DOS command

[Jamaika]

Hi
If anyone still remembers DOS?
I can't save the echo command with two variables. How does it properly save?

echo %audio%t%%

[Bjs]

What is it your doing ?

Via batch script or similar in dos prompt (arrow up should return last dos prompt used)

You can get an idea from this

Yes, I do. It was a 16-bit operating system which was reduced to a mere bootloader for Windows 95, 98 and M.E.

In other words, the image below is not a "DOS prompt" at all

Thanks for the reply.

What is it your doing ?

I am trying to write my own converter mkv to mp4 with the possibility of transferring attachments. I used DOS, long time, and hence problems. I should learn C ++, but it's too difficult for me. I have Windows 8.1.

set w=0
set z=0
set /p srt= < %file%_format_audio.txt
set str=%str:,/=,und/%
echo.%srt%> %file%_format_audio_mod.txt
del %file%_format_audio.txt
:label2
set /a id1=1+%w%
set /a id2=2+%w%
set /a id3=3+%w%
set /a id4=4+%w%
set /a t=1+%z%
echo %id1% %id2% %id3% %id4%
for /f "tokens=%id1%,%id2%,%id3%,%id4% delims=,/" %%a in (%file%_format_audio_mod.txt) do (
echo %%a %%b %%c %%d
if [%%b]==[AAC] set codec2=aac
if [%%b]==[AC-3] set codec2=ac3
set /a m=%%a-1
set id=%%a
set lang=%%c
set ida=%%d
)
ffmpeg -y -loglevel warning -i "%file%" -f %codec2% -map 0:%m% -c:a copy -vn -sn -dn -map_chapters -1 -map_metadata -1 %file%%t%.%codec2%
if [%codec2%]==[aac] set audio%t%=-add "%file%%t%.%codec2%:sbr:lang=%lang%:trackID=%id%:name=(Audio %t%)"
set audio%t%=-add "%file%%t%.%codec2%:lang=%lang%:trackID=%id%:name=(Audio %t%)"
if [%codec2%]==[] set audio%t%=""
echo %audio%t%%
set w=3
set z=1
if [%ida%]==[%id4%] goto label2

not sure what you want to do, if you want to print variable "audio" and "t" it should be:
echo %audio%%t%
or with some space between those:
echo %audio% %t%

I want to be able to display the values of "audio1" to "audio100", where %t% is the second value from 1 to 100.
I don't want two separate values.

echo %audio%%t%
or with some space between those:
echo %audio% %t%

[ndjamena]

CALL echo %%audio%t%%%

or

SetLocal EnableDelayedExapansion
echo !audio%t%!
EndLocal

Thanks. Finally properly displayed.
