The command -syntax- is your friend when facing this kind of problem.
See: -help syntax-, and the example below:

*----------- begin example -----------------
capture program drop foo
program foo
    syntax [, bla(string) blup(int 0) ] 
    di as txt "option bla contains " ///
       as result "`bla'"
    di as txt "option blup constains " ///
       as result "`blup'"
end

foo
foo, bla("bar") blup(4)
*---------- end example ---------------------          
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
Maarten
