Dynamic Variable(s)....Help??

[toshk]

now I have all these dynamic variables....
efficient way to delete them or purge them when not needed....help?? efficient app function.
example....
if I do create say v1...v10 for 10 node circuit with their calculated values assigned. and also their corresponding potential differences say v1v2 ,v2v3......assigned.
how do I delete/purge all these variable(s) efficiently for my next circuit run. cos this time the circuit has only 5 nodes.
