[ADMB Users] a conditional statement under PARAMETER_SECTION

[Saang-Yoon]

Hello, Steve.
Thank you very much for your prompt response, which is helpful.  By
the way, the conditional statement in your example is used below
"init_bounded_matrix_vector sel_par".   Now if we want to ignore the
parameter vector, "sel_par" by an option, then we may want to put the
parameter declaration ("init_bounded_matrix_vector sel_par") under the
optional statement, which would lead to a compile/link error.  I
wonder about how you or others get around in "one" TPL file.  Again
thank you.
