I am embarking on my first programming exercise with stata, and would appreciate a little advice. The task involves getting a model command to iterate a number of times with a sub-set of the independent variables being systematically modified each time using different values of a scaling factor (say going from 0 to 5 in increments of 0.1). I need to retrieve the log likelihood of each model, and display them alongside the corresponding values of the scaling factor. In this way the scalilng factor that results in the model best fitting the data can be obtained.

I am sure this is all possible, but having read the material in the users' guide on programming stata, I cannot see a simple way of storing the different values of the log likelihood in an array (I know that this is very straight-forward in most other programming languages), so that they can be conveniently displayed after the model runs have been finished, for instance by looping a display command over all the values contained in the array.
Along the lines of my post to Statalist on 4 Jun 2004, please see

http://fmwww.bc.edu/ec-c/s2004/771/movingwindow.do

which stores scalar results from a sequence of OLS regressions in an array.
