Hi, I've started working with arrays, and here are two small issues or questions. 1. The help for 'genr' says: "In the appropriate context, series, scalar, matrix, string and bundle are synonyms for this command." It seems this statement has to be amended with the array correspondences, 'matrices', 'strings' (and 'bundles'?), as in: "matrices mymarr[3] = zeros(1,1)". (I also noted that using 'matrix' doesn't work here which is ok I guess.) 2. If 'checks' is an array of matrices, is this supposed to work? (It doesn't in the current snapshot.): "print checks[3]" 3. Then there is another thing related to bundles, see this example: <hansl> bundle bcheck = null matrix bcheck.mymat = ones(1,1) bcheck.mymat ~= zeros(1,1) </hansl> which gives me a "~= not implemented for this type" error. So a matrix inside a bundle somehow isn't a first-class matrix it seems. (The workaround "bcheck.mymat = bcheck.mymat ~ zeros(1,1)" works.) 4. Also bundle-related is a very weird behavior where gretl doesn't acknowledge the bundle it just created: <hansl> stop = 10 loop i=1..stop --quiet bundle bSim = null bSim.p = 2 endloop </hansl> tells me "bSim: no such object"!!?? Notice that the wrapping loop seems to be necessary to provoke this error. thanks, sven
