Block structures are identified by '''(...)''' and '''^{...^}'''. The difference between the two structures is that commands into a '''(...)''' block are executed into a distinct process. In this case it means for example that environment modifications will not be seen into the main process. Look at these scripts: {msh> set A=1 msh> ( 1> (( A = $A + 1 )) 1> print $A 1> ) 2 msh> print $A 1} {msh> set A=1 msh> ^{ 1> (( A = $A + 1 )) 1> print $A 1> ^} 2 msh> print $A 2}
