I would like to write a macro that generates a `struc`. The actual macro is larger and more complex, but the "problem area" boils down to the following:

Code:

macro define_a_struc name, [params] {
common
  struc name

forward
  params,  ; I am getting an error "unexpected characters" here when I try to use the macro.

common
  \{

forward
  dd params

common
  \}
}

As you can see in the code above I am trying to generate a list of parameters for `struc` from the macro arguments. Initially I thought the trailing comma was the problem, but even removing it and limiting to just one single parameter still results in a compile error. Clearly there's something I'm missing here. Any ideas what could be wrong?

I should have mentioned that simply doing

Code:

...
common
struc name params \{
...

doesn't work for what i'm trying to do. i need to do some additional stuff to each param within that `forward` block.

Code:

macro define_a_struc name* { struc name \{
  match title par,name \\{ irp arg, par \\\{ dd arg \\\} \\}
 \} }

define_a_struc  <test2 abc, def, ghi, jkl>
label2          test2  123, 456, 789,  0
