I want my subcircuit to have variable/parameter/value. Something like
every resistor has resistance.. So, when I draw schematics, its very
easy to change resistor value and each and every resistor can have
different value. I want that same thing for my .subckt and not to have
to make different model for every possible value.

for eg. this is what i got and it works real nice:

.SUBCKT KP_XN _ssi_pin0 2
* _SS_Symbol [C:\Program
Files\AnaSoft\SuperSpice\System\SchematicBlocks.ssm] [2PinBlock]
B1 _ssi_pin0 2 I=13.5/V(_ssi_pin0,2)
.ENDS

but I wish for  something like this:

.SUBCKT KP_XN _ssi_pin0 2
* _SS_Symbol [C:\Program
Files\AnaSoft\SuperSpice\System\SchematicBlocks.ssm] [2PinBlock]
B1 _ssi_pin0 2 I=a/V(_ssi_pin0,2)
.ENDS

and to be able to change value of a when drawing schematics the same
way I change value of ordinary resistor.
Is it possible?

TIA
