Dear Domingo,

I do not yet understand what was you weren't able to express with the
current syntax.

Instead of

if length(p) == 3 then display "true 3"; else display "false 3";
if length(p) == 5 then display "true 5"; else display "false 5";

you can write:

param p,symbolic := "dad";
display if length(p) == 3 then "true 3" else "false 3";
display if length(p) == 5 then "true 5" else "false 5";
solve;
end;

Best regards

Heinrich
