When you -generate- a variable, you implicitly apply a "function" to all
observations. If you want to write your own function, -egen- is a good
starting point, and this is explored in the article cited above...

Betreff: st: Should be simple yet ... how to write a function?
Im a pretty advanced Stata user, but have a simple question I cant figure
out: how does one write a *function*, i.e. a program that returns a value,
and that can be called like local y = fct(x), where x and y are numbers or
strings.
This seems it should be available somewhere in the language, yet I?ve
searched in a lot of programming explanations about Stata and never found a
way to write that. FYI, I program extensively in stata, know about r-type
vs. e-type program, and know how to store results to return to main program.
I just don?t know how to write the most simple function form.
Any idea?
Fabrice
