Or, if your index is something like of a geometric series as it seems to be (let's say 6, 12, 24, 48, and so on) and too long to do manually you can try this one: <script> scalar count=0 loop for (count=6;count<=24;count=count*2) --quiet <instructions> endloop <\script> cheers, artur Riccardo (Jack) Lucchetti a écrit : > On Tue, 25 May 2010, Henrique Andrade wrote: > >> Dear Gretl Community, >> >> I'm trying to use a loop index inside a script but I don't know how. >> According >> to "Gretl User’s Guide" the syntax looks like this: >> >> loop i=1..24 >> >> But I just need the points where "i" is equal to 6, 12 and 24. >> Something like this: >> >> loop i=6;12;24 >> >> How can I do that? > > For example, this way: > <script> > matrix foo = { 6, 12, 24 } > n = cols(foo) > loop for i=1..n > bar = foo[i] > print bar > end loop > </script> > > > Riccardo (Jack) Lucchetti > Dipartimento di Economia > Università Politecnica delle Marche > > r.lucchetti(a)univpm.it > http://www.econ.univpm.it/lucchetti > ------------------------------------------------------------------------ > > _______________________________________________ > Gretl-users mailing list > Gretl-users(a)lists.wfu.edu > http://lists.wfu.edu/mailman/listinfo/gretl-users _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
