Re: [ns] Wired nodes in the mixed networks

[Waleed Numay <numa8091@bachman.ou.edu>]

lindex: is the name of the command
$temp:  is the name of the array
$i:     is the index of the array

for example:

set temp (1.2.2 1.2.3)
set i 0

then 
lindex $temp $i
is the first element of the array temp which is 1.2.2.

hope this help.
