Hi Johnoel,

   I actually discovered the problem on my own... I did not realize that the
function call was written in my own GLOBAL_SECTION.  I have another question

   We are attempting to run simulations of a statistical model, and to
benefit our arguement... we would like to make an external call to ADMB's
Quasi-Newton Optimization routine.

  We have created our own C code that has implemented the Preliminary
Calculations and established the 'Negative Log-Likelihood' (f), but we would
now like to call ADMB's Quasi-Newton Methods to optimize that Negative
Log-Likelihood and return the Result vector with the  'Optimal Parameter

  Is this possible to do?  And/or do you understand what we are trying to
