In -dirifit- (downloadable from SSC) I stored the number of depedent
variables in a global $S_k and the file dirifit_lf.ado started with:

*! MLB 1.0.0 23 Mar 2006 
program dirifit_lf
        version 8.2

        local alpha_k "ln_alpha1"
        forvalues i = 2/$S_k {
                local alpha_k "`alpha_k' ln_alpha`i'"

        args lnf `alpha_k'

Hope this helps,
