Ok, so I remembered some things correctly (see below), but indeed had
forgotten the most important part: It's already there! Just push the
"lags" button in the VAR specification dialog and enter your individual
lag structure (comma-separated I think).
See http://lists.wfu.edu/pipermail/gretl-devel/2009-February/001682.html
for the original discussion, already four years ago... time passes
quickly...
It remains to be said that the CLI version is still undocumented at
least in the online help.
