gSystem->Exec() : memory of variables

Hello,

in root, there are the methods TSystem::Exec() and TSystem::GetFromPipe which have the same behaviour for the following issue :

if one does in unix :
a=3
echo $a
it works

but in root :
if ones does :
gSystem->Exec("b=3);
gSystem->Exec("echo $b")
it will "forget" the b

only this works :
gSystem->Exec("c=3;echo $c")

==>

is there a way to have the memory of the variables for several gSystem->Exec() commands ?
(in order to do some instructions ones, and some others inside a loop)

(i tried also with export, but it doesn't help)
