Dear Statalisters,

I am trying to understand a do file where the underlying data has the 
variables B1 and B2 which are both equal to 0 for all observations.
After the programm -mlblub- is defined, it is used in the -ml- framework 
in the following way:

-ml model lf mlblub (A1: B1=one, nocons) (A2: B2=one, nocons), maximize 
search(off) difficult trace init(2 1, copy) technique(dfp)-

I have two directly related questions.
1. What is the function of the B1=one and B2=one terms in the equation?
2. If I run the the -ml- line I get the error message "initial values 
not feasible" r(1400). Is that because of the 0 values in B1 and B2?
