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

[toshk]

how can i create a dynamic variable.?
Application:
in circuit simulation application (eNet) http://www.hpmuseum.org/forum/thread-7015.html i was able to generate a column dynamic matrix (nkll) for a given network.
nkll consist of node voltages and currents thru a branch variables. (but they were never declared as a variables in the application );
now i want to assign values (solutions) to nkll matrix in the application....help?
the goal here is designing a scope for these nodes:
