what do you mean by "a general smooth function" -- you might want to try searching "spline" (though Dupont's program is not included in the results for some reason) and you might want to look at -fracpoly- and at -mfp- in the reference manual

I want to do a Cox regression with a continuous covariate, call it EF,
and I want a general smooth function rather than a simple linear form
for EF vs. the proportionality constant. Is there a way to specify such
a form for a covariate in =93stcox=94? Or is there some other way to get a
smooth for a continuous covariate in Cox regression? The =93Introduction
to Survival Analysis in Stata=94 book doesn=92t cover this.
