Hi, after a long pause I have been trying to put together a function package again. Unfortunately, it failed, and it looks like a bug to me. This is with 1.8.3 both on Windows and Linux. I'm attaching a trivial example of when the bug happens, named 'toplevel.gfn'. Nevertheless, it could be that it isn't even a minimal example; I'm using a helper function 'secondlevel' in the package, haven't tried if that is really necessary to trigger the behavior. This package returns (or should return) a matrix. And if the functions are run in a script everything works as expected. But in reality nothing happens, even if I specify a name in the dialog for the new matrix to be created from the return value. thanks, sven P.S: I noticed that the function namespace is still quite flaky. For example after an error happens in a top level calling function due to a bug there, rerunning the corrected version often leads to a situation where second level functions that are called aren't being recognized by gretl anymore, although nothing was changed in the second-level functions. ('Unknown symbol such_and_such') This really reduced productivity when developing scripts because gretl needs to be closed and restarted quite often.
