Solve : imbricated variables?

Answer»

I try to resolve imbricated variables :

set a=temp
set b=%a%

I'd LIKE te resolve something like %%B%% (I use this in a for loop because I have a set different variables)

but ECHO %%B%% just SAYS %a%

I try to PUT this this way

for %%i in (%%B%%) do ( .....

how can DOS solve "a" USING the "b" variable as input ?


a little error

I meant

set b=a
and I'd like to resolve

so %b% = a
and I'd like te resolve %%b%% = %a% = temp

sorry for the error
