[Gretl-devel] Midas and join (or append)

Hi, I will be working with Midas in gretl again soon, and I've just reread (or let's say, re-browsed) the midas_gretl.pdf guide. Looking at the section "importation via join", it occurs to me that this is quite involved. In contrast, "importation from a database" is very simple. Shouldn't it be possible to just do something like this: <hansl-future> open AWM.gdt # quarterly join hamilton.gdt EXRITL --compact=spread # monthly to quarterly </hansl-future> or perhaps the 'append' command is better suited than join here? So replace the last line above with (which however gets all series, but that's OK): append hamilton.gdt --spread I guess this append thing would basically be a syntactic shortcut for this block (more or less): pd = $pd store temp.gdt # the currently active dataset open hamilton.gdt --preserve dataset compact pd spread store tempcompact.gdt open temp.gdt append tempcompact.gdt I'm ready to consider working more with the database storage format (which I almost never have done), but is the above suggestion unreasonable? thanks, sven
