pspice netlist

Hi, can anyone tell me how to enter a circuit as a netlist in orcad and simulate it? I tried entering it in textfile with .cir extension but the simulation comes back with "simulation aborted because no device was found in schematic". thanks.
I like schematic capture but I couldnt find a current controlled switch that would turn on and off for few cycles. I dont think there exists one, because everyone seems to type in a code for it.

Please don't post a question in multiple forums at the same time.
