Set the result of a command in a variable

Solved
Shooter78 -  
Bonjour,

I would like to know how to store the result of a command in a variable?
Here is the command in question: "wmic csproduct get identifyingnumber"
Since the result is on 2 lines, I only want to retrieve the second line in my variable.
Thank you in advance.

    I finally managed to do what I wanted.
    Here is the code to obtain the serial number: 
    FOR /F "tokens=2 delims==" %%B IN ('WMIC csproduct GET identifyingnumber /VALUE ^| FIND /I "IdentifyingNumber="') DO SET serial=%%B

    Here is the one for the PC model: 
    FOR /F "tokens=2 delims==" %%A IN ('WMIC csproduct GET Name /VALUE ^| FIND /I "Name="') DO SET machine=%%A


    Thanks Dubcek for your help.

        Hello,

        I'm getting this: 

        C:\Windows\system32>for /F "delims=" %a in ('wmic csproduct get identifyingnumber') do set t=%a :\Windows\system32>set t=IdentifyingNumber :\Windows\system32>set t=XXXXXXXXXXX :\Windows\system32>set t= C:\Windows\system32>echo %t% ECHO command enabled.


        I think that since there are multiple lines, it redefines the variable for each line.
        Any ideas?

        Thanks again for your help.

        P.S.: XXXXXXXXXXXXX being the line I wish to retrieve.

          `%a contains each line, my command stores in t the last line, therefore the second one.
          remove your sets`

            The underlined lines are the result of the command; it is not me who put the SET.
            According to the result, there apparently should be 3 lines (one of them empty?), which would explain why in the end I get ECHO enabled instead of the serial number 

            C:\Windows\system32>for /F "delims=" %a in ('wmic csproduct get identifyingnumber') do set t=%a  :\Windows\system32>set t=IdentifyingNumber :\Windows\system32>set t=XXXXXXXXXXX :\Windows\system32>set t= C:\Windows\system32>echo %t% Command ECHO enabled.


            Thank you for your help.

              Possible indeed, if there is an empty line, it is necessary to have the second to last one
              which Windows? I have XP
              what does the command display (with line numbering) 
              wmic csproduct get identifyingnumber | findstr /n "."
              put do @set t=%a so that the sets do not appear

                I have Windows 7 pro x64.
                Here is the result of your command: 

                1:IdentifyingNumber 2:XXXXXXXXXXXX


                So apparently there is no 3rd line.
                Strange.
