st: different stcox output when used in a program

[Michael McCulloch <mm@pinest.org>]

Using the same simple stcox command, Stata 9.2 outputs the hazard 
ratio when I issue the command, but the coefficient when I use it 
within a program. I'd like to learn how to obtain the hazard ratio 
within my simple program.

FROM COMMAND LINE:
.   stcox tcm if stage==1
------------------------------------------------------------------------------
          _t | Haz. Ratio   Std. Err.      z    P>|z|     [95% Conf. Interval]
-------------+----------------------------------------------------------------
         tcm |   .7800136   .2798863    -0.69   0.489     .3860754    1.575913
------------------------------------------------------------------------------


FROM PROGRAM:
.         program define bootgcomp
  1.                 stcox tcm if stage==1
  2.         end
.         set seed 12358
.         bootstrap, reps(1000): msmcox_stageII
------------------------------------------------------------------------------
             |   Observed   Bootstrap                         Normal-based
          _t |      Coef.   Std. Err.      z    P>|z|     [95% Conf. Interval]

         tcm |  -.2484439    .351693    -0.71   0.480    -.9377495    .4408616
