Thanks Maarten,Sound really a good idea! Just a follow up question. I am trying to checkwhat the code does and therefore look into the macro `u_k' to make sure itcontains what I want. In this simple case I want it to contain "u1 u2 u3".So I am typing:----- clear scalar u1 = 1 scalar u2 = 5 scalar u3 = -1 local u_k "u1" forvalues i = 2/3 { local u_k "`u_k' u`i'" display `u_k' } display `u_k' -----Why when I ask Stata to display the macro content inside the loop it worksfine but when I ask it just after the loop, Stata does not return anyvalue?I guess this is probably a naive question from a beginner Stataprogrammer, sorry!Cheers Carlo -----Original Message-----From: owner-statalist@hsphsun2.harvard.edu[mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Maarten buisSent: 18 February 2009 13:33 To: stata list Subject: RE: st: multivariate normal regression with ml, linear form --- Carlo Fezzi wrote:I don’t know how to define the args. For example, if it is a bivariate equations it would be mu1 mu2 lnsigma1 lnsigma2 r12, but for a 4 or 5 equations model it would have of course more arguments. I guess it could be a function of the global var neq, but I don’t know which is the correct way to specify the args.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, Maarten ----------------------------------------- Maarten L.
