[Gretl-devel] Older discussion at gretl-users & Bundles

Hi there, I did now find the time to go through my many questions and your many answers again, to do as Sven suggested (quote) and opened a few tickets. However, I have some more general remarks on my recent experiences with bundles (which are great!), which I guess are better posted here. Consider a list C in bundle B which is again located in bundle A. At some point, when passing a bundle by reference to a function and then passing a part of that bundle by reference to another function, a list that was part of the bundle became undefined (the lest went away). I cannot reproduce this and perhaps I remember wrong. However, a bit of the story I can reproduce: <hansl> nulldata 100 series A = normal() list L = A bundle boo bundle coo boo.coo = coo eval inbundle(boo,coo) boo.coo.L = L eval inbundle(boo.coo,L) function void testA(bundle Bndl) eval inbundle(Bndl,L) #eval argname(Bndl.L[1]) #error eval varname(Bndl.L[1]) #OK end function function void testB(bundle *Bndl) eval inbundle(Bndl,L) #not OK end function testA(boo.coo) #OK catch testB(&boo.coo) #not OK </hansl> Including lists within bundles allows to do operations like sampling and manipulating series located outside the bundle (which is great!), also varname(C[1]) would return the variable name of the first element in list C. So basically this is a way to pass a series by pointer, which is very useful. Perhaps this should be mentioned in the references? Best Frederik
