Thanks Al! Ok, I confirm it looks better with a .verilog at the start.
Also had a quick look at the wiki now:
http://gnucap.org/dokuwiki/doku.php/gnucap:manual:languages:verilog

But trying to run a simple sweep on the Resistor gives:

.verilog

param w=2

module m(1,2);
   resistor #(.r(w*5)) r(1,2);
endmodule

m #(.w(w)) m1(0, 1);

// sweep dc voltage
vin  1  0  dc 3

.dc vin 0 5 0.2


default plugins: cmake-2 2017.10.18

param w=2
^ ? p: no match
m #(.w(w)) m1(0, 1);
                 ^ ? m: 1); has no value?
// sweep dc voltage
^ ? /: no match
vin  1  0  dc 3
