Dear listers:

I am aware of previous posts regarding nlcom and use of macros. My
problem is different.
I have included sample output:

 regress rpcinc lgini

      Source |       SS       df       MS              Number of obs
=    2688
-------------+------------------------------           F(  1,  2686) =
5411.08
       Model |  8.0104e+10     1  8.0104e+10           Prob > F      =
0.0000
    Residual |  3.9763e+10  2686  14803795.6           R-squared     =
0.6683
-------------+------------------------------           Adj R-squared =
0.6682
       Total |  1.1987e+11  2687  44610141.6           Root MSE      =
3847.6

------------------------------------------------------------------------------
      rpcinc |      Coef.   Std. Err.      t    P>|t|     [95% Conf.
Interval]
-------------+----------------------------------------------------------------
       lgini |     107085    1455.75    73.56   0.000     104230.5

       _cons |   -34119.9   689.5794   -49.48   0.000    -35472.06
-32767.74
------------------------------------------------------------------------------

. nlcom log(lgini)

expression (log(lgini)) evaluates to missing
r(498);


Clearly, the problem is in my usage of nlcom syntax. Is it the case that
nlcom is more stringent than test command? I am familiar with test and
have not had this problem.

Again, I see nothing in the manual/help to steer me, but I know I am
messing something up.

Any help, as always, is appreciated.
