I don't think I should be struggling with this, but I have a module
that requires a diameter and a height for a cylinder.
I would like to call it with a vector; something like this:
specs=([20,5]); product(specs);
Then in the module product(), I would like to do something like
cylinder(d=diameter,h=thickness);
My problem is getting the two cylinder values out of the vector.

You seem to be using an object variable so I think you can use
specs = object(a=[220,5]);
product(specs);
module product(specs) {cylinder(d=specs.a.x, h=specs.a.y);}
but why not keep it simple and use
specs = [220,5];
product(specs);
module product(specs) {cylinder(d=specs.x, h=specs.y);}
(remember .x and .y index the first and second elements of a vector)

I'm sure there are smarter people than me here, but when I define
vectors, I write
specs = [20, 5];
Perhaps the parentheses are the culprit.
Then I would say, in module product(s)
cylinder(h = s[0], d = s[1]);

you can call the subroutine name(va,vb); where va and vb are then locals
to that subroutine if the module line opening the sub looks like this:
module name(va,vb) where you have previously defined or calculated the
values in the calling module. Then you can call the cylinder macro with
h=va,d=vb and it will use the passed values for your cylinder.. You can
pass a rather lengthy list of named variablesthat way.

Thanks all! For some reason I thought the parentheses were needed.

They are neither needed nor harmful.
