Doesn't work is not informative enough, we need to know 
exactly what you typed, what you expected Stata to return, 
and what Stata actually did return.

Given what you told us I can only give you this pseudo-code
that you might or might not be able to adjust to your 
problem

levelsof day
foreach day in `r(varlist)' {
    ml model lf my_prog_lf (y=x) (x2) ... if day == `day', maximize
}

Hope this helps,
Maarten
